Due to the presence of viruses, driver or software mismatches, the OS may malfunction. If your Windows crashes, don’t rush to panic. The situation can be corrected by returning the state of files and programs to the moment when the PC was working properly.
While running OS Windows 7, 10 or 8, certain errors and problems may occur. As a result of such failures, starting the operating system again in operating mode becomes impossible. In this case, it is not at all necessary to do a time-consuming reinstallation of the OS. All you need to do is perform a system restore.
Recovering the OS using the recovery environment
When working we use the following scheme of actions:
- Reboot the computer, press the F8 key while loading;
- Troubleshooting;
- System restore, selecting an OS restore point;
- Click "Further" and again "Further";
- Press the button "Ready", we reboot the system (in the Menu, select boot with the last successful configuration).
Windows 7 System Restore
There are several methods you can use to get your OS running again. Some of them rely on rolling back to saved settings. Others simply clear the data.
You can “reanimate” the OS in one of the following ways:
- by selecting restore points;
- using the command line;
- through safe mode;
- using a recovery environment;
- using an image/boot disk.
Restoring the operating system using system “resuscitation” checkpoints is one of the most affordable, effective and popular options. To apply it, you need to make a series of clicks:
- Panel "Start";
- "System Restore";
- "Further";
- "Select a restore point";
- "Ready".
With such an operation, problems with the computer will be corrected, changes will be canceled and the system will be returned to the operating state that allowed the PC to boot normally. There is no loss of data, files and documents with this type of recovery. All data is saved. The operation is reversible. You can roll back the system to a previous computer state and use a different restore point.
Many people wonder how to make a recovery point on their own (manually) in order to choose it in the future? To do this in the same menu "Start" - "System Restore" You can create such a point yourself at any time convenient and suitable for you. It will be saved indicating the current date, which you just have to remember.
From restore point
In computer engineering there is such a thing as a recovery point. These are saved PC settings. As a rule, saving occurs automatically with each successful OS boot. The easiest way to restore Windows 7 is to use this data.
Press F8 when your computer boots. This command will bring up a menu of system startup options. Next, you need to select the Last Known Good Configuration option.
Another method can be used. Go to the properties of the My Computer folder. Find the line System Protection, clicking on which will open the dialog box of the same name. Click Recovery – Next. We set a target date, indicate the disks that need to be fixed, and confirm the actions. After rebooting, the PC should work normally.
No restore points
You can fix problems with the OS even without restore points. To do this you will need to resort to the LiveCD program. You need to download it and burn it to a flash drive with the .iso extension.
Further all actions will take place in the BIOS. You need to configure booting from a flash drive. To do this, in the Boot section, select USB-HDD in the First boot device line.
Before proceeding directly with the recovery, copy all the necessary files to a removable disk. The LiveCD program provides a special menu for these purposes.
We will fix the system error using an archived copy. Connect the USB flash drive, open the Windows\System32\config\ folder. Files with the names default, sam, security, software, system must be moved to any other folder. In their place, transfer similar files from the RegBack folder and restart the computer.
The described method will only help if the problem is related to the registry.
Command line
You can resort to “reanimating” Windows 7 from the command line if the PC begins to freeze or works slowly, however, the system still boots. Enter the menu "Start" and using the right mouse button, launch the command prompt as administrator. Run the rstrui.exe command, which will open the system restore program. Click "Further". In the next window, select the desired rollback point and click again "Further". Once the process is complete, the PC should work normally.
There is another way to access the utility. Let's go to "Start". To open the command line, click "Run" and enter the CMD command. We click on the found CMD.exe file and wait for it to launch. Next, enter rstrui.exe in the command line and confirm the action with the Enter key on the keyboard.
It is not always possible to play it safe and create OS restore points in advance. Problems may arise that block the option of such “reanimation” of the PC. Then you can use another, no less effective and easy option - restoring the Windows system using the system itself.
We rely on the diagram:
- Icon "My computer"- right mouse button "Properties";
- "System protection";
- In the new window click "System protection", recovery button;
- "Further";
- Select a restore point according to the date;
- Specify the system disks to be restored;
- We confirm the operations and reboot the system.
Restoring Windows 7 using Safe Mode
This method is preferred if the usual system boot is impossible. Then after pressing the PC power button on the system unit, hold down the F8 key to call "Start Menu". One of the "Menu" options is "Safe mode". Select it and press Enter on the keyboard. As soon as Windows boots, we carry out the algorithm of actions that we described earlier.
System recovery Windows 8/8.1
If you managed to start the OS, you can resume Windows 8 via "Options". Hover over the top right corner and enter them. Click on "Change computer settings" – . Chapter "Recovery" will offer several options:
- "Regular recovery with information preservation".
- “Deleting data and reinstalling the OS”.
- "Special option".
Decide what exactly needs to be done. Next, follow the menu prompts.
If you choose the latter method, in the window that opens, click on the diagnostics item. You will be offered the following options:
- "Restore";
- "Return to original state";
- "Extra options". This item includes the ability to roll back to the desired resume point.
To resume Windows 8.1, press Win+R and call sysdm.cpl. In the system properties window in the tab "Protection" specify the required system drive. Click "Restore". Clicking "Further", you will be able to see a list of rollback points. Select the one you want and click "Search for affected programs". Changes that have been made to the PC since the selected moment will be deleted. Complete the process by clicking "Ready".
If you work with Windows 8, problems may occur, the Internet may not work correctly, etc. To fix this, you can use the classic recovery method through restore points.
Another option is a system rollback. To do this, open the menu "Start" - "Control Panel" - "Windows Update". Select an item "Removing updates". The same can be done using the command line.
So, in the list of updates that opens, we delete those from the moment of installation of which (we look by date) problems and malfunctions began. We delete unnecessary files and reboot.
You can perform a factory reset on Windows 8.1. Important files will not be affected during this operation. The method is effective, but to implement it, the OS needs to boot without problems. We use the algorithm:
- Right side of the monitor - "Options";
- "Change settings";
- "Update and Recovery" - "Recovery";
- "Recovery without deleting files".
If you cannot log into the system in the usual way, you must use the disk with the system. Load the installation disk, select "System Restore". Press the button "Diagnostics", And "Restore".
Windows 10 System Restore
If you have problems with Windows 10, press Windows + Pause. Go to "System protection" and press "Restore" – "Further". Select the desired indicator and click again "Further". When finished, click "Ready". The computer will automatically restart and the changes will take effect.
One of the advantages of the “ten” is the ability to return the settings to factory settings. This helps avoid having to install the system all over again. To reset your data go to "Computer Settings" – "Update and Security" – "Recovery" – "Return the computer to its original state". Click "Begin".
You can take care of the possibility of a rollback in case of failure in advance. You can create resume points yourself or configure their automatic creation at the desired frequency. To do this, in the settings, in the Update and security item, select Backup service. Specify where to save copies, click Add disk. After selecting the device, the function will be activated.
You can restore your Windows 10 system again by using restore points. In this case, the system will be rolled back to the moment when it loaded smoothly and worked without failures. This recovery method is described at the beginning of the article.
If the OS does not boot, a warning table with a key appears on the screen "Additional recovery options". Click it and select "Diagnostics" - "System Restore". We select a Windows restore point, wait for the system to roll back and reboot.
If such operations do not help and the computer continues to work incorrectly, you can roll back to the basic settings. Some programs and utilities, personal PC settings will be reset, and personal data will be deleted.
This technique is used extremely rarely if the other options described above do not help. The algorithm of actions is as follows:
- "Start" - "Selecting parameters"- tab "Updates and Security";
- Paragraph "Recovery"- button "Begin";
- We choose to delete all files or keep some of them.
Recovering the system after this will take 40-90 minutes.
Resuming using the installation disc
One of the radical methods of fixing the error involves using an installation disk. After launching it in BIOS, click System Restore. In the Troubleshooting section, specify the desired action. Next, follow the system prompts to complete the process.

Often, users of computers running Windows 7 encounter problems with the operating system. Problems with your computer usually appear when it slows down a lot and programs won’t open. Also, the computer may not start at all or may do so every once in a while.
The reasons that cause problems in the performance of the operating system can be very different. For example, if a computer gets hit virus, it can damage system files. Also, difficulties with the PC may appear during installation low-quality software, which can damage the structure of system files. To solve a problem with the performance of a computer on Windows 7, you need to roll back to the previous one. recovery point.
To protect the OS, Windows 7 uses restore points that the system periodically creates. Essentially, restore points are previous state of Windows 7 system files. To help Windows 7 PC users, we have prepared material that will describe the detailed process of restoring the system in various ways.
Restoring performance in a busy seven
If your computer running Windows 7 boots, but the system is not stable, then it's time to roll back to a previous restore point. First of all, we need to get to the window where we can call up the system recovery options. To do this, open the program “” by pressing the key combinations Win + R, through which we enter the following command: systempropertiesprotection
A window should open in front of us “ Properties of the system" on the " tab System protection" You can also get to this window in the standard way through the menu “ Start". The next action is to press the button Recovery….
After clicking, the System Restore window will open. It will ask you to restore the system using a recommended access point or select another one. We'll stop at recommended restore point.
This window requires confirmation for the selected recovery. To confirm, click the Finish button.
This button will bring up a message warning that after the recovery procedure it will be impossible to return to the previous parameters of the seven. By clicking Yes in the message, we will begin restoring the Windows 7 system.
If the process of returning to the previous state occurred without errors, a corresponding message will be displayed.
If you are unable to roll back to previous settings using the recommended point, then you should select the point that was created later than the selected restore point Windows 7 systems. I would also like to note that to perform this operation you will need special privileges. That is, when you log in, you must select an account admin and enter a password for it.
Restoring the computer's functionality when the OS starts
If your PC is running seven at all is not downloading, then you can start the operating system in safe mode. After the BIOS start window appears, press F8 on the keyboard (for laptops there may be another key, for example, Del or one of the function keys). This action will cause menu of alternatives loading seven.
In this menu, select the item “ Safe mode" and continue by pressing Enter, after which the system will start in safe mode.
If the system successfully started in safe mode, then start restoring the seven, as shown in the previous example. In this mode to ensure maximum security many functions disabled OS, including the Windows Aero graphical interface. This is what the running program “” with the command “” will look like systempropertiesprotection"on a system running in safe mode.
We return the computer to functionality using an installation disk or bootable USB flash drive
If the previous two examples do not help you, then you will need to restore seven installation disk or flash drive. For computers that do not have an optical drive, you need to use a bootable USB flash drive with the OS. A bootable USB flash drive can be created using special utilities. The most popular utilities for this purpose are Windows USB/DVD, Download Tool And Rufus.
Boot from the installation disk or via a USB flash drive. In the installer start window, click Next and proceed to the next window.
After searching, select the OS you want to restore and click Next.
In the window that appears, select the same item “ System Restore».
This action will launch the Seven recovery utility. In the utility, click Next. This action will take you to list of recovery points. Let's choose a suitable point and continue.
A window will appear in front of you, as in the first example. Therefore, we click the Finish button and respond to the message, after which we will start the recovery.
After a successful rollback to the previous state, you will receive a message like this.
Emergency recovery of Windows 7 using antivirus
If your PC is infected viruses that interfere with the proper operation of the computer and the first three examples discussed do not help you, then a good recovery method in this case would be an anti-virus life disk from Dr.Web. With this disc you can clean the system of all types of dangerous software. In addition to cleaning, Dr.Web LiveDisk will be able to cure infected objects, which are necessary to restore Windows 7.
The Dr.Web LiveDisk image can be used both for recording to an optical disc and a flash drive. To use Dr.Web LiveDisk on a USB drive, you will need a special program. You can download the program for recording onto a flash drive and the image itself on the official website by going to www.freedrweb.ru/livedisk.
Let's run the recorded image on disk, setting it to boot first in the BIOS.
In the bootloader start window, select first item Dr.Web LiveDisk and press Enter. These actions will start loading Dr.Web LiveDisk.
After downloading Dr.Web LiveDisk, we will get a full-fledged Linux-based operating system. As written earlier, the main purpose of Dr.Web LiveDisk is to clean and treat virus software. Therefore, this OS has a built-in antivirus Dr.Web CureIt!. This antivirus runs with the OS.
Click on Dr.Web CureIt! button Start scan, which will start scanning, cleaning the system and disinfecting viruses.
After checking, Dr.Web CureIt! will remove or cure infected objects.
Since there will no longer be malicious code in the system, you can safely restore the system in the three ways described above.
If, after checking the system files, you are unable to restore your Windows 7 system, then the only reasonable solution is to make a complete backup of the information and reinstall the system again.
How to make a system image in seven
Another recovery feature in Windows 7 is creating a system image. In this image, you can save all the information on your hard drive, including the operating system. After restoring using this method, you will receive an OS with the same parameters as on the day the image was created.
Run " Control Panel" and go to the tabs " system and safety», «»
In the window that opens to create an image, indicate the location to save it and click Next.
In the window that appears, all that remains is to click the Archive button, which will start the image creation process.
You can restore the created image with Windows 7 and all the information on local disks using the installation disk. The recovery principle is shown in the second example, only when choosing a recovery method you need to select " Restoring a system image" and indicate its location on the saved drive.
Alternative methods to restore the Windows 7 operating system
In addition to standard recovery methods, there are alternative software that perform the same function. The most interesting solution that allows you to perform system recovery is the program Acronis True Image 2016. This is a proprietary software package from Acronis.
First of all, download and launch Acronis True Image 2016 from a shortcut on the Desktop. When launched, the program will ask for a name and password.
Now let's set it up Acronis True Image 2016 so that he can do backup of the entire disk with Windows 7 OS. This setup should be done immediately after installing the OS, so that while using Windows you can restore functionality from several backup copies of the system created over a certain period of time. So, let's start setting up. To do this, select the storage type by clicking on the “” link.
In the window that opens, select the storage “ Acronis Cloud».
Now let's create a schedule for our backups. To do this, press the button “ Options" and let's move on to the storage settings settings. On the first tab, select the schedule you like for creating backups of our system.
As you can see, the entire computer is selected as the backup source. Therefore, in the schedule we set, a backup copy of the system will be created in cloud storage " Acronis Cloud».
For an example of recovery, let's take an archive copy not from the Acronis Cloud cloud storage, but from the hard drive. If you have created a backup copy on your computer, then Acronis True Image 2016 he will find her himself.
So we press the button Restore your computer, after which the program will completely restore the system to the state it was in when the backup was created. Also, if you cannot start Windows 7 on your computer, Acronis True Image 2016 There is a boot image for this that can be burned to disk.
You can download this image from your account page. You can obtain a password and login on the official website www.acronis.com. The principle of operation of the bootloader is the same as with the desktop version. Load disc from Acronis True Image 2016 on your computer you can by setting it in the BIOS first when booting.
From the example it turns out that the utility allows Full control over the creation of PC recovery copies and back up your entire system to the cloud.
An example of launching an Acronis True Image 2016 boot disk
To launch the disk Acronis True Image 2016 When starting the system, you must set the boot mode from optical drive first in the BIOS. For example, for the MSI A58M-E33 motherboard, these parameters in BIOS mode look like this.
Another boot method is to use hotkeys to call up the drive boot menu in the BIOS. For example, for the MSI A58M-E33 motherboard, the hotkey is the F11 button. By pressing this button, we will launch a special mode in which, when the system starts, it will open drive boot menu in BIOS.
After booting from the Acronis True Image 2016 disk, we will be taken to this menu.
In this menu you need to select Acronis True Image 2016, after selection the program will start.
The example shows that launching a boot disk Acronis True Image 2016 Using the required BIOS mode is not at all difficult.
Let's sum it up
In this article we have discussed almost all the methods and parameters system recovery. We also looked at ways to restore the seven using alternative software and using an antivirus. Which method to choose to restore Windows 7 depending on the situation is up to you.
To summarize, I would like to note that they mainly disrupt the operation of the OS viruses and experiments with different illegal software. Therefore, so that you do not have to constantly restore the system, use only proven and licensed software, and also use reliable comprehensive anti-virus protection.
I would also like to note that the examples discussed in the material will work not only on Windows 7, but also on more modern operating systems, such as Windows 8 And 10 . And we, in turn, hope that our material will allow you to properly restore Windows 7 and you can confidently say that I can perform a system restore.
Video on the topic
Restoring Windows 7 is a reconstruction of the computer's system files that corresponds to a specific period in the past. This method is the best way to resolve a problem associated with incorrect installation of a program or driver, when removing the application that caused the application to slow down, freeze, or otherwise fail does not allow the OS to be returned to a working state. Sometimes restoring Windows 7 helps even in cases where the system is not able to boot at all. Another name for the Windows recovery procedure is System Restore.
There are three ways to restore Windows 7 - using the utility built into the system, using the system installation disk, or System Restore through safe mode. In this article we will look at each of them.
Restoring Windows 7 using the built-in utility in the system
Restoring Windows 7 using the system itself is only possible if the system files have not been damaged and the OS boots normally after turning on the computer. Find the My Computer icon and right-click on it and select Properties. In the window that opens, go to the System Protection tab.
You will see the System Properties window with the System Protection tab open.
Click on the Restore button. After this, the Restore System Files and Settings utility will be launched.
Click "Next. You will be taken to a window with a list of all existing restore points. To display them all, check the box next to “Show other restore points.” Select the restore point you need and click Next again.
In the next window, you will need to select the state of the system files of which disks you want to restore. Usually it is enough to restore the system drive C. After checking the necessary boxes, click Next again.
A final window will appear in front of you, summarizing all the information about the recovery point: the date it was created and a brief description of what changes to the system it was created in connection with. Here you can also create a password reset disk. A similar “floppy disk” can be created using any modern FLASH media. You may need this information if you forget your system password.
After you click the Finish button, a warning window will appear informing you that it will not be possible to abort the restore operation once you decide to start it. To continue the utility, click Yes.
After this, the system will begin returning to the selected restore point. Initially, all documents and applications will be closed, and the computer will restart. If no errors occurred during the System Restore process, you will see a window with information about the successful restoration.
System Restore via Safe Mode
If an operating system error has caused Windows to not even boot, the above method will not help you. However, you can try to restore Windows 7 using safe mode, which often boots even when the normal system boot does not work.
To enter Safe Mode, restart your computer and press the F8 button several times when it starts. A window will appear in front of you with a list of additional OS boot options.
Using the cursor keys, select any Safe Mode boot option and press the Enter key. After Windows 7 boots into safe mode, follow the same steps as in normal system mode.
Right-click on the My Computer shortcut and select Properties. Then select the Control Panel section from the list.
A window will appear in front of you where you should click on Start system recovery. You can also configure System Restore settings by clicking on the Advanced recovery methods link.
After this, the application will launch, the operation of which we discussed above.
Follow the same series of steps as described in the first system recovery method.
Recovering using a Windows 7 disc
In some cases, the operating system may refuse to boot into safe mode, then the second recovery method will also be impossible. However, if you have a Windows 7 installation disc available, you can try to fix the problem that caused the system to crash. A similar disc in the form of an ISO image file can be downloaded on the Internet, and then burned to a regular DVD.
Before you begin restoring the system, you must set boot priority from the DVD drive in the BIOS settings. After this, you should insert the Windows 7 boot disk into the drive and restart the computer. A black window will appear in front of you with the inscription Press any key to boot from CD or DVD... Press any key, after which the information will begin loading from the disk.
It will take some time before Windows downloads the necessary files.
In the window that appears, configure the language, keyboard layout and time format. After you click Next, the Windows 7 welcome window will appear. You need to click on the System Restore link. After this, the System Recovery Options window will appear in front of you.
You will see a list of Windows 7 recovery applications. First, it is recommended to run the Startup Repair utility, which will help fix problems that interfere with normal system booting.
If this does not help, go to the second point, System Restore. After this, you will see the Restore System Files and Settings utility, the features of which we discussed above. If this utility also does not help bring the system back to working condition, you can try the System Image Restore utility. However, this method can only help you if you have made an image of your system in advance.
How to create a restore point in Windows 7
In order to easily restore the system after a crash using the system utility, you should create a system restore point in advance at a time when no problems were observed in its operation. It's very easy to do. To find the utility you need, simply type “Create a restore point” into Start.
By clicking on the name of the utility, you will be taken to the System Protection window. There you need to click on the Create button.
In the small window that appears, enter the name of the point in order to distinguish it from others in the future.
The restore point has been created.
Creating a system image in Windows 7
A more reliable way to restore Windows 7 is to use a system image, which can help restore the operating system even if it does not boot. To create a disk image, enter “Backup and Restore” in the menu bar. Click on the name of the utility, a window will appear in front of you.
Click the Create a system image link on the left side of the window. The system will scan your computer for media that can save the system image and offer you a list of them to select. In total, Windows 7 has three options for saving the image: on one of the hard drives, on a DVD, or in a network location.
Select the media that is most convenient for you and click Next. If there is not enough space on the specified hard drive, the image will not be created, so do not worry that the application will fail.
If there is enough space on the hard drive, archiving will begin - a very long and resource-intensive process. Since the utility's work may take several hours, the most convenient solution would be to leave the computer overnight.
System recovery is important when the PC suddenly slows down, incorrect optimization and a number of other reasons that there is no time or desire to understand. Let's look at the main ways to restore Windows 7.
How to restore Windows 7
It is worth noting that when restoring the system, the user does not lose personal files, so there is no need to worry about the safety of your documents, photos and other content.
First way : Restore the system using the system utility.
This is a Windows component that is as simple as possible to manage, so there should be no difficulties during operation. To launch it, click Start and in the search bar we begin to write System Restore. The search engine must find this phrase before you add it. Let's open it.
The window that opens introduces you to the System Restore Wizard. Click Further.
Select the restore point closest in date to the current one and click Further.
Note: if you are worried about what will change when you roll back to the selected point, then you can view what will change when you restore. To do this, select the desired restore point and click the button Find affected programs.
If the displayed restore point does not suit you, check the box next to the option Show other restore points.
After you have selected a point, the wizard will require you to confirm the action with a window like this.
Click Ready.
Click Yes.
Now all you have to do is wait a while until the system configures everything itself.
After the reboot, the system will notify you that the operation was successful.
If the system notifies you of an error during recovery, or the action did not bring the expected result, select another recovery point.
Second way : System recovery via safe mode. It will help when the system refuses to start in normal mode. To enter Safe Mode, start your PC and once it starts to boot, keep pressing F8 on keyboard. From the black window with download options that opens, select Safe mode.
After downloading, do the same as described in the first method.
Instead of safe mode, you can choose Safe Mode with Command Line Support.
As soon as the command line opens, write in it rstrui.exe. A window with the System Restore Wizard will open. How to work with it is described in detail in the first method.
Third way : System recovery via boot disk. It is suitable only for those users whose installed operating system is located on a CD/DVD disk. To do this, insert the disc into the drive, and in the BIOS settings, set it to boot from a CD/DVD disc
Note: BIOS versions may vary. PC boot settings may differ for each version. But for most users the algorithm is the same. First, start your PC and immediately start pressing the Delete or F2 key on your keyboard. Then:
- In the window, follow the chain Advanced BIOS Features - Boot Sequence - First Boot Device and select CD/DVD.
- Press Esc then F10. A window will appear confirming saving the settings. Press Y.
- Follow the chain Boot - Boot Device Priority - 1st Boot Device and select CD/DVD.
- Press Esc then F10. A window will appear confirming saving the settings. Click Ok.
- Go to the Advanced tab, select First Boot Device and select boot from CDROM.
- Go to the Exit tab and select Save & Exit Setup. A window will appear confirming saving the settings. Press Y.
After this, it should start from the boot disk. In the window that appears, select the language and click Further.
After that, press the button System Restore, which is located at the bottom of the window.
A window with recovery options will open. Choose System Restore and click Further.
Select a restore point (more about it is written in the first method) and click Further. The recovery wizard will ask you to confirm the action, click Ready and wait until the system recovers.
When working in Windows 7, serious errors may occur, after which the operating system simply stops starting in normal mode. However, this is not yet a reason to take out the Windows boot disk from a dusty corner to reinstall it. Win 7 has a Recovery Environment in its arsenal - a powerful tool that will help restore the previous state of the operating system, avoiding the loss of data on your PC or laptop. In addition, other tools for resuscitating Win 7 are available to users.
Windows 7 system recovery methods
You can revive Win 7:
- using a restore point;
- using safe mode;
- via the command line;
- through the Recovery Environment;
- using a disk with a Win 7 image;
- using the Win recovery disk.
Rollback to a restore point from Windows
If the OS boots normally, but you need to restore it to its previous state using a restore point, do the following:
Rolling back the operating system to a restore point will allow you to remove the software that caused problems with your PC, undo unwanted changes and return back to the state of the operating system when everything worked correctly and booted properly. And just as important: there will be no data loss, and all your recent documents will remain in place. Some files may remain duplicated, slightly changing their name. You can delete unnecessary copies of these files yourself.
Note: This process is completely reversible. If necessary, you can cancel it and restore the Windows 7 system using another point.
Reverting the operating system in safe mode
This Windows 7 system recovery method is almost identical to the previous one. It is used in situations where Win does not start in normal mode:
Running Win 7 recovery from the command line
In some cases, when Win 7 does not start in any mode other than safe, the following method helps: restoring the Windows 7 system using the command line. You can do it like this:
Reverting the OS state through the Recovery Environment
The Windows 7 recovery environment includes 5 tools that offer the PC user various ways to troubleshoot problems related to the performance of a computer running Win 7. It is created automatically in a hidden partition. This happens when installing Win 7, be it “Maximum” or any other version.
To restore Windows 7 using this method, do the following:
Note: the first step is to start the OS with the last known good configuration.
The operating system automatically remembers the parameters of the last successful start of the PC in normal mode and applies them when you select this option. As a result, you can quickly regain access to the system without the slightest loss of data. If this method helps a PC user solve the problem, the question “How to roll back a Windows 7 system?” will immediately stop bothering you.
Restoring Win 7 using an image disk
This method of resuscitating Windows will allow the operating system to return to its lost functionality, even if it categorically refuses to start in safe mode. You will need a bootable DVD with your version of Win 7 installed.. If there is no OS image on your PC, create one yourself. To do this, go to the control panel and select “Backup computer data”. Then select the option indicated in the screenshot below and follow the instructions. 
Recovering Win 7 using a recovery disk
If, after pressing the F8 button, you do not find the line “Troubleshooting computer problems” in the list, restoring Windows 7 using a system repair disc will help. This happens if the user accidentally deletes the recovery environment partition, which is located in the Recovery directory of the system local disk. Do you think the only thing left to do is uninstall Win 7 and install it again? This is not necessary - the changes can be undone without having to reinstall the OS.
