How to restore the system. Last Known Good Configuration
I would divide the system recovery methods into the following:
1 Using Last Known Known Configuration
2 Using the "System Restore" mechanism normally
3 Using the system recovery mechanism not normally (via safe mode or original installation disk Windows 7)
4 Using a previously created system backup.
1) Suppose you encountered a problem with Windows 7 and wanted to restore the system, the simplest thing you can do is boot into Safe Mode and load the last known good configuration, to do this, press the key when loading the operating system "F8" and select "Last good configuration» , press "Enter".
Last Known Known Configuration is a recovery option designed to boot your computer using the last known working system settings. Booting in Last Known Good Configuration mode restores information system registry and driver settings that were used the last time the system booted successfully. Use Last Known Good Configuration mode when Windows boot 7 in normal mode impossible as a result of incorrect changes.
2) If the first method is not suitable or did not help, you can restore the Windows 7 system using the " System Restore» The operating principle of this recovery method is quite simple; recovery occurs thanks to created points recovery. A restore point fixes the system state to certain moment. Restore points are created automatically by the system, but they can also be created manually (this is the subject of this article). There are several ways to run System Restore - The first method is to click "Start" and write in the search bar "System Restore", a menu will appear at the top "System Restore" click on it with the mouse.
The second way is to go along the path "Start-Control Panel- Recovery - Startup system recovery". A window will open "System Restore", press "Further", you will see everything possible points restorations to which you can return/“roll back” if you press the button "Search for affected programs", you can see which programs will be affected by system recovery (I recommend choosing recovery two or three days before the system problem). Having selected the date, click "Further".
Confirm the restore point by clicking "Ready"
Then a message will appear stating that System Restore cannot be interrupted, click "Yes", after which the process of restoring and rebooting the system will begin. 
After the reboot, if the recovery is successful, a window will appear. 
3)
If you have suffered from a virus and you do not have the opportunity to start system recovery using the above method, then you can “roll back” the system using Safe Mode or using a disk with the operating system: We go into safe mode (by pressing "F8" at the very beginning of system boot) and select "Troubleshooting your computer", a window will open
- We insert the original installation disk with the operating system (it must match yours), boot from this disk (to do this, in the BIOS we change the boot from hard drive to boot from CD/DWD). Select the language, then in the window "Windows Installation", choose "Recoverysystems".
After this a window will open "Recovery Options" Windows systems 7".
So, no matter which method you used, the result is the same - you have a window in front of you "Windows 7 System Recovery Options",
I propose to analyze a little the capabilities of this window.
Startup recovery- analysis of faults that interfere with the normal loading of Windows 7 and their further correction for normal loading and functioning of the operating system.
System Restore- this is why this article was written, with the help of this function we can use a restore point to return the system to an earlier period of time when there were no problems.
Restoring a system image- this tool allows you to restore the system from a backup. This method is described in more detail in recovery method 4.
Windows Memory Diagnostics- checks system memory for errors.
Command line- allows you to download command line and with its help you can delete files that interfere with loading Windows 7.
Click on "System Restore", after which a window appears stating that "rollback" system can fix problems... click « Further", select the required restore point.
After this, we agree with everything proposed, including rebooting, and as a result of all these actions, when loading Windows 7, we see a window
4)
Restore using a previously made backup; creating a backup is described in more detail in the article. Connect USB device backup storage, click "Start" - "Control Panel" - "Recovery". If the system does not start and there is no way to boot the system, you must follow the third point of the article, just select Restoring the system image.
In the window that opens, select " Advanced recovery methods".
Then a window will appear asking you to reboot the system, click " Restart".
After restarting, you must specify system recovery settings. I recommend leaving everything as default and just clicking " Further".
In the next step, the system itself will find the system archive.
Next, you can specify additional parameters.
After that, confirm your choice and press " Ready".
Confirm system recovery by clicking " Yes".
If all of the above methods did not help you, then all that remains is to return the Windows system to factory settings, i.e. lose all your data and programs. I’ll say right away that this method This will work if you have a hidden recovery volume on your hard drive, it should be provided from the factory. You can see it if right click mouse click on the shortcut "Computer" and select « Management- Management disks"
Below are the hotkeys for restoring laptops to factory settings:
- Acer- press the key combination Alt+F10
- Samsung- F4;
- Dell inspiron - when the dell.com splash screen appears, you need to type the key combination Ctrl+F11;
- HP Pavilion- when turning on, hold F11;
- Packard Bell - F10;
- Rover- when starting the laptop, hold down Alt;
- ASUS- when the ASUS logo appears, press F9;
- Sony vaio - at startup press F10;
- MSI- press F3 when starting;
- Fujitsu Siemens- after turning it on, press F8;
- LG- F11;
- Lenovo ThinkPad - F11;
- Toshiba- F8.

There are many ways to restore the OS. But no matter how reliable they are, it is advisable to prevent system failure. And then the question of how to restore Windows 7 will disappear by itself.
Users often experience situations when, due to the installation of a certain driver, utility, or virus infection, the OS begins to slow down terribly or does not function at all. Thanks to the program's recovery option, system files can be restored to normal. In this way, you will be able to avoid the lengthy process of fixing breakdowns. In some cases, the issue can be resolved only by delving into the BIOS system; in others, more help will help simple tools, for example, a boot disk. To understand how to restore Windows 7, spending a minimum of time, study this material to the end!
The most simple option recovery is a system rollback
Experts identify a number of methods by which the OS can be restored to its correct state. The list looks like this:
- system backup (backup);
- applying the last known good system configuration;
- disk with system installation files or use safe mode(non-standard mechanism);
- standard “System Restore” mechanism.
Last Known Good Configuration
This is the most basic way to restore Windows operation 7. To do this, you need to boot through safe mode (the computer is rebooted, and at the stage of turning on the OS, press F8). The window that appears in front of you will list different variants downloads. The “Last Known Good Configuration” section will help you by selecting it and pressing Enter.
The section is needed so that the user can boot the PC using the latest, adequately working parameters. Often, with the help of such simple manipulations, it is possible to restore driver settings and system registry data. The function helps when the OS cannot be loaded in standard mode due to incorrect changes.
Recovering from Safe Mode
First you need to go to Windows safe mode (F8 key). After waiting until the machine boots up completely, go to “Start” - “Search” and look for the “System Restore” program. All that remains is to select a point and confirm the decision. We'll talk about what a restore point is later.
If the method helped, then last stage The computer will reboot on its own, and then restore its operation in the mode that is familiar to you.
Boot disk
The method is great for those who have an original disk with Windows 7 OS on hand. It will help restore the system when even safe mode does not help. Let's look at the procedure:
- press F8 to switch to safe mode;
- select “Troubleshoot your computer” and then “System recovery options”;
- insert the disk, boot from it (read below how to do this);
- select a language, go to the “System Restore” section in the “Windows Installation” window.
After these simple manipulations you will be taken to the section with parameters Windows recovery 7, where you can return everything to its place by selecting the correct point.
Boot priority in BIOS
The boot order allows the computer to understand which device to boot the OS from. Having chosen the order, the user can boot from different media: from a flash drive, disk, over the network.
So, to change the order, you first need to go into the BIOS system. Most often, this requires pressing F2 or Del. You need to press it when a message like “Press Del (F2) to access the BIOS” appears on the screen.
On some machines, other combinations are used: Ctrl+Alt+Esc, F1, or just Esc.
Once in the BIOS, you need to go to the Boot tab. Transitions between menu items are performed using the left and right keys. The decision is confirmed by pressing the Enter key.
Next, it is important to find the Boot Device Priority item. Now all that remains is to select the order of devices by changing them by pressing the “-” and “+” buttons. Having set the necessary parameters, it is important to save the changes and leave the BIOS (Save & Exit tab).
Restoring using backup
If you have previously created a system image, then the method will be truly life-saving. Find the backup and do the following:
- connect a flash drive with backup;
- select “Recovery” in the “Control Panel” menu (opens through “Start” in safe mode);
- Restart Windows 7.
If it is impossible to boot the system, then you can use the backup only by booting through safe mode (F8) and selecting the “Restore system image” item.
When installing an image via safe mode, it is important to select the “Advanced recovery methods” options, and there find the option to use a system image. The computer will prompt you to back up, you can skip this point and just reboot. If you leave the recovery settings at their defaults, Windows will recover after a reboot.
System Recovery Options window
It doesn’t matter which method you used to restore the OS, you will go to this window. There are a number of functions here that are important to know about:
memory diagnostics Windows - by selecting this item, the computer will check the system memory for errors;
System Restore - return of Windows for a period when there were no defects;
startup recovery- analyzes defects through which the usual system boot cannot take place;
command line- the ability to delete files that prevent the system from booting;
system image recovery- allows you to resume normal work OS from a previously prepared copy.
After going to “System Restore”, a new window will appear, where there will be a message stating that to eliminate all current issues"System Rollback" will help. Click Next and select a point.
Restore point
A correctly working OS creates such points without your help, this happens every 7 days. They are also created when updating drivers or installing software components. Such points can be set manually if desired. Need to:
- save and close all files;
- go to “Start” - “Search programs and files”, where enter “Create”;
- go to “Create a restore point”;
- click “Create” in the “System Protection” window;
- describe the name of the point so that you can find it in the future.
After selecting a description to identify the point, the creation process will begin, after its completion the system will issue a corresponding notification.
Return to factory settings
If it was not possible to achieve a clear result, then you need to “reset” to initial settings. This option is used on laptops. It is very controversial, because all data on the machine will be lost. In addition, the method can be implemented if there is a hidden volume on the hard drive (provided from the factory). You can find out whether such a volume exists by clicking on the “Computer” shortcut and selecting “Management” - “Disk Management”.
To return Windows to factory settings, you need to hold down a certain key (the algorithm is different for each device model).
Here is the list of keys:
- for MSI laptops - hold down the F3 button at startup;
- Samsung - F4;
- ASUS - F9;
- Acer - Alt+F10 (hold);
- Toshiba - F8;
- HP, LG - F11;
- Dell - Ctrl+F11.
Results
Restore Windows work 7 is easy. One of the methods presented here will certainly help restore the system to its correct state. This is the use of the last known good configuration, recovery via safe mode, boot disk and backup. Extreme measures- reinstall Windows again or roll back to initial settings, but you will lose data on the disk where the OS used to be.
Write in the comments which method was the most effective!
Friends, I have long promised my regular readers to write an article about system recovery. Many of us have already encountered this situation more than once when we install some program, make some operating system settings, accidentally delete service files and do much more, which ultimately leads to incorrect and unstable functioning of the OS.
Today I will tell you? What needs to be done to return the operating system to working condition.
Friends, don't forget that hopeless situations can not be.
The algorithm discussed below will be useful to everyone. There are no people who don’t make mistakes and always do everything right. As wise people say: “Only those who do nothing make no mistakes.” But you should also be able to correct mistakes.
And for everyone who wants to find out, if necessary, cancel recent actions on the computer, I wrote a detailed algorithm.
Recovery checkpoint
So, Friends, check Point recovery is a copy service files operating system, program settings, as well as the system registry at a certain point in time.
The operating system, as a rule, creates recovery checkpoints automatically at certain intervals, in the case of installing any software or at the direct direction of the user.
It should be noted that when “rolling back” to the operating system restore point, the user’s personal files, such as music tracks, graphic files, documents, etc.
Attention! Returning to a restore point allows you to restore the OS, but not personal content user.
1. Click on the “Start” button at the bottom right of the screen and select “Control Panel”. The main Control Panel window of the Windows 7 operating system will open:
2. Click on the very first section “System and Security” and in the window that opens, select the subsection “Restore the computer to a previous state”.
3. In the window that appears, click on the “Start system recovery” button.
4. The system will collect necessary information and launch the System Restore Wizard. In the first window that appears, you just need to click the “Next” button.
5. Next, the second Wizard window will open, where you need to select a restore point from the list provided. If you have just made some settings and want to cancel them, then select the top one the specified entry. You can also select any recovery point entry that suits you.
You can also run “Search for affected programs” by clicking on the corresponding button. The operating system will scan its service records, determine which programs will be deleted or restored during a rollback to a restore point, and present the analysis results in separate window. After reviewing the lists of affected programs, click the “Close” button.
7. A warning window will appear on the screen that it will be impossible to interrupt the system recovery. And once again they will ask you to confirm your intentions by clicking the “Yes” button.
After this, the system recovery process will begin. Which usually takes a little time - about 2-3 minutes. After which the system will reboot and you will see this window:
Your computer has been restored to the specified state. Now you can check the operation of the OS and other programs to ensure they are working correctly. Be sure to test the result of the system restore.
If operating system failed to restore the system, then the window will be different. This often happens when working antivirus program. Disable it and try again.
If you were able to successfully solve the “” problem, then I congratulate you. But in some cases, restoring the system did not lead to an improvement in the situation, but rather to its deterioration. The system began to freeze, some programs would not load at all, desktop icons disappeared, etc. In this case, it is best to cancel System Restore.
To do this, we carry out the entire algorithm, starting from point 1. When you complete step 3, the following window will open:
Select “Cancel system restore” and then follow the algorithm presented above.
So, Friends, we've covered quite a bit important question“how to restore the system?”, learned to “roll back” the system to restore points and cancel “rollbacks”.
It should be noted that restoring the system in the specified way possible, but only if it wasn’t serious damage system files, for example, as if the system is infected with a virus. In case of serious violations of the OS this remedy is ineffective and you cannot avoid resorting to one of the advanced system recovery methods.
In one of the following articles, I will talk about just such a tool - an emergency recovery disk.
