Download windows 8.1 system recovery. Windows System Restore. Roll back Windows through restore points

The registry is a large database that stores all the parameters necessary for the normal operation of the operating system. You can view it through the registry editor, which is available in Windows. Any user can enter it if his account has administrator rights.

And if you made any changes, or the computer turned off by itself, for various reasons, or you accidentally pressed the wrong key and deleted a parameter or a whole registry branch, then this may not have the best effect on the computer's operation.

And yet, if this happened, let's figure out what are the ways to recover. windows registry 7 and Windows 8 for normal computer operation.

Using a backup

As you probably guessed, this way will fit not everyone. If you have previously created backups registry through "File" - "Export" - read on, if not - go to the next method.

So, you have a backup copy. Press the combination Win + R, the "Run" window will open. In the "Open" field, write regedit and click "OK".

The Registry Editor window should appear. In it, go to the "File" tab and select "Import" from the menu.

An explorer will open, find the previously created backup in it and click "Open".

Wait for the files to be copied.

Using system restore

System restore can be done using restore checkpoints. You could create them earlier, when the system was stable and you were satisfied with everything. Or they could be created automatically by the system: when making changes to the computer configuration, before installing drivers, and so on.

Consider first, how to restore the registry if the operating system boots... In Windows 7 go to "Start" - "Control Panel".

Here we are interested in the item "Recovery".

In the next window, click "Start System Restore".

Now you need to select a restore point. If there are several points, and you are in doubt, look at the date the point was created - did your computer work normally on these numbers ?! - choose her. By clicking Find Affected Programs, you can see which programs will be removed as a result of the recovery. Click "Next".

We confirm the rollback of the system to the selected state by clicking "Finish".

All data, including the registry, will correspond to the state that was at the time of the creation of the selected restore point.

If you have Windows 8 installed on your computer, read the article: Windows 8 restore point and system rollback. There you will be interested in the second part. The actions will need to be performed the same as described above.

If the OS won't start

Repair the registry if the computer does not turn on you can too. In the Windows 7 operating system, when the computer boots up, press the F8 button at intervals of 1 second. A window will appear "Additional download options"... In it, use the arrows to select the item "Troubleshooting computer problems".

In the next window, select your language and click Next.

Select your account, it is better to have administrator rights, then enter the password, if you have it set when you log in, and click "OK".

The following window should appear, select the item "System Restore".

A recovery window will open, click "Next" in it and repeat the steps described in the paragraph above.

If you have Windows 8 installed on your computer, you can press F8 or Shift + F8 when booting, but the window for additional download options is unlikely to appear. It is best to use a system repair disc or bootable USB drive... You can create them on any other computer with Windows 8 installed.

Follow the link and read the article on how to repair Windows 8. Everything is described in detail there. The following window should appear. Then follow the path: "Diagnostics" - "System Restore", and select the desired restore point.

Through the command line

In Windows, the files that are responsible for the operation of the registry are stored in the following path: C: (the letter of your system drive) / Windows / System32 / config. There is also the RegBack folder, which stores backup copies of all registry branches. They are updated by the system automatically, depending on the settings, every 5-10 days.

We need to do the following: delete the DEFAULT, SAM, SECURITY, SYSTEM, SOFTWARE files that are in the config folder and replace them with similar files from the RegBack folder.

We will not be able to do this in the operating system, since it will be necessary to replace the files responsible for its operation. Therefore, you need to use additional boot parameters, and open command line.

In Windows 7, press F8 when booting the system. Then you need to do everything as described in the paragraph above. In the window System Recovery Options, select item "Command line"... As a result, the command line will run as administrator.

In Windows 8, you can open the command prompt using the combination. This is detailed in the article: Windows 8 Safe Mode. Read the point: go to safe mode using the combination Shift + reboot. When the following window appears, select "Command line".

If the computer does not turn on at all, due to changes in the registry, then read the point: go to safe mode using a system recovery disk (you can create it on any computer with installed Windows 8).

So, we launched the command line. Now we enter the following commands line by line there. Press Enter at the end of each line. First, let's create a badreg folder on the system drive, copy all the files of our non-working registry into it. Then we can safely delete the DEFAULT, SAM, SECURITY, SYSTEM, SOFTWARE files from the config folder, because we have copies of them. Finally, copy the backups from the regback folder to the config folder.

MD c: \ badreg
copy c: \ windows \ system32 \ config \ default c: \ badreg
copy c: \ windows \ system32 \ config \ sam c: \ badreg
copy c: \ windows \ system32 \ config \ system c: \ badreg
copy c: \ windows \ system32 \ config \ security c: \ badreg
copy c: \ windows \ system32 \ config \ software c: \ badreg

delete c: \ windows \ system32 \ config \ default
delete c: \ windows \ system32 \ config \ sam
delete c: \ windows \ system32 \ config \ system
delete c: \ windows \ system32 \ config \ security
delete c: \ windows \ system32 \ config \ software

copy c: \ windows \ system32 \ config \ regback \ default c: \ windows \ system32 \ config \
copy c: \ windows \ system32 \ config \ regback \ sam c: \ windows \ system32 \ config \
copy c: \ windows \ system32 \ config \ regback \ system c: \ windows \ system32 \ config \
copy c: \ windows \ system32 \ config \ regback \ security c: \ windows \ system32 \ config \
copy c: \ windows \ system32 \ config \ regback \ software c: \ windows \ system32 \ config \
exit

After you enter the exit command, the command prompt window will close and the computer will reboot.

I hope one of the ways will help you restore the registry in the Windows 7 or 8 operating system.

Under the concept of "restoring Windows 8", users often mean different things: someone just restoring factory settings, and someone - removing previously installed updates or canceling changes that occurred after installing a suspicious driver. Today it is customary to consider several useful methods that will help you roll back the OS. Windows versions 8 and 8.1. We will talk about them in today's article.

It is not necessary to reinstall the system to return the PC to work.

These points are very often used to get the system back on track. They are created without the participation of the user, after installing various utilities, drivers, etc. You can create them yourself, manually. The method helps in situations when errors occurred when loading or operating the machine after installing a program.

You can use the method like this:

get to the control panel (first select the "Start" button), click "Recovery";
click on "Start System Restore";
enable the renewal process by selecting the point of interest by the date.

Canceling updates

Sometimes, after installing basic updates, our computer starts behaving incorrectly: the Internet may disappear, errors appear when working with individual programs. To avoid such a development of events, experts recommend using the rollback of updates. Recovery of Windows 8.1 using this method is pretty quick. To do this, use the Center Windows updates, where click on "Remove updates". Alternative way- apply the command line.

So, after going to the Update Center, you must select the link " Installed updates". All updates installed on this moment, their installation date and code. Having figured out after what period the problems with the machine began, calculate the update and delete it by pressing the appropriate key. The PC will ask you to confirm your decision, to do this, click "Yes".

Now reboot the system - this will help you understand if the error has disappeared or you need to look for another way out to solve the problem.

Recovery image

To rollback to normal, the system may need a backup with all drivers, programs, and, if necessary, files. Such images are present on all devices on which the manufacturer installed the OS. The images are located in a hidden section of the hard drive, contain the programs installed by the manufacturer, as well as the system itself.

The user can create such an image on his own at any time. It is best to do this after installing and performing basic settings. If the hidden section is missing or was previously deleted, you can recreate it.

So, you need to select "Delete all files and reinstalling Windows"In the" Recovery "section. No preparation is required, because everything is done automatically.

Reset

At wrong work a computer running under Windows version 8 (8.1), you can "drop" the basic settings, while your important files will not be deleted. It is preferable to do this when all other options have not helped. The method is highly efficient, but you can only use the reset if Windows starts up by itself.

In the panel on the right side of the monitor, find "Settings" and then find the item "Change settings". Next, it is important to select the "Recovery" section in the "Update and Recovery" list.

The following options are offered here:

deleting all files and reinstalling Windows;
recovery without deleting files (what we are interested in now);
special download options (not relevant to this article).

If you click on the second option, you will reset all system settings without affecting the files that are on the computer. In other words, videos, documents, music and a number of other downloads will remain intact. However, third-party utilities that you installed yourself will be removed. Programs from the Windows 8 store will be reinstalled automatically.

The first step will allow you to return the car to factory settings. By choosing it, you may lose important data. If the disk is split into a pair of disks (C and D, for example), then non-system partitions can be left intact.

Clarifications:

When performing a factory reset, the computer uses the recovery partition, which is present on all devices with Windows preinstalled. If the OS is installed on its own, a reset is also possible, but you have to use the distribution kit of the installed Windows, from which the necessary files will be taken.

Many users upgrade to version 8.1 after receiving Windows 8. After resetting the settings, they need to update again, because in this case you will receive a "clean" version. In the process of performing these steps, you may need a product key (the system may ask you to enter it at one of the stages).

If you can't log in

If nothing loads, the user can get to the update mechanism (to do this, find the disk with the system). The procedure is as follows:

boot from installation disk or a previously created recovery disc, click "System Restore";
find the item "Diagnostics", then click on the "Restore" button.

As you can see, you just need to find the required disk and the problem will be solved. After completing these steps, you will have the correct version of the OS, and a report on the programs that had to be removed will appear on the desktop.

Outcomes

Recovering Windows 8 or 8.1 is possible even in the most difficult situations. All that is required for this is to study the instructions presented above and follow each of its points. We hope that one of the proposed methods will help solve the problem by saving important files on your computer. Good luck!

As we mentioned earlier, in some cases, when inconsistencies in the registry are detected, for example, inaccurate data were recorded, the system will try to heal itself during the boot process.

Although poorly written software or the driver does not actually pollute the registry, they, with their chaotic areas, which, when available, create systemic problems lead the registry to an unstable state. Windows provides several useful tools to get the registry up and running, including System File Checker, Chkdsk, System Restore, and Driver Rollback. You can also use third-party utilities to repair, clean and defragment the registry.

The System File Checker (SFC) is a fairly old tool still used on modern operating systems and relies on the administrative command line to do its job. SCF verifies the integrity of each existing within the facility Windows system file including Internet Explorer.

A damaged Windows system file leads to system instability and security vulnerabilities, as well as suboptimal performance during normal operation.

To call the SFC, follow these steps:

Insert DVD with installing Windows(but don't run).
Open an administrative command prompt.
Type sfc / scannow and press Enter.

SFCs are bundled with all versions of Windows, but if you are trying to run SFC on a system updated with one or more service packs, you will have to prepare a DVD (or ISO image) with installation files Windows that include service patches. This is for the SFC to check and use SP versions of the system files to replace damaged ones.

Attention... It takes a long time to check the SFC. SFC, to ensure the integrity and recovery of the found damaged system file, checks each file on the system.

The SFC is not intended for regular troubleshooting use, only consider it when you encounter system instability issues.

Another well-known tool, Check Disk (ChkDsk and Chkntfs), scans hard drives computer for errors and fixes them. The launcher requires administrator credentials as it runs at low hardware level and needs to have special disk access in case of installation problems.

To run ChkDsk, open an administrative command prompt, type the following command and press Enter.

Running the ChkDsk program on the system drive will schedule the task at the next system reboot.

Any HDD that stops reading or writing data correctly is likely to corrupt files on the system. Typically, if the system detects corrupted data files, this leads to some loss of them and ultimately to a demand from the user to restore their files from a backup or file history. You should be interested in carefully saving the registry files, as this can cause the system to freeze or worse, crash.

Whenever Windows tries and cannot read data from a corrupted system file, paging file, or registry, Windows displays an error message commonly known as blue screen of death. If this happens, you should immediately determine whether it is an isolated occurrence or a blue screen is an early sign of a probable disk failure, leading to the proliferation of file corruption and Windows instability. A media failure may seem catastrophic and it is, but it will generally display the aforementioned errors for a while, which is a typical symptom of bad unusable sectors. Majority bad sectors the result of physical damage such as overvoltage, physical damage, or manufacturing defects.

Software tools such as ScanDisk and CHKDSK are offered to the user to attempt data recovery. As a rule, once identified broken sector, the system marks it as bad and excludes its use for data recording.

On Windows 8.1, the Chkdsk tool works automatically in background and actively monitors the health of NTFS volumes.

If the system detects a damaged file, NTFS under Windows OS solves most problems on its own, without requiring additional special tools, for example, a recovery disk.

Attention... Under normal operating conditions, if you are using Windows 8.1, you will not need to run Chkdsk, as the operating system itself monitors file system for damage, and the hard disk for bad sectors and fixes problems in the background.

CCleaner

Although we have already talked about the popular CCleaner tool from Piriform before, in this article it is worth remembering it again in relation to solving general issues of registry destruction.

As mentioned earlier, if you install or uninstall any software application or a device driver, problems with the remaining fragments of incomplete or obsolete entries are inevitable.

Ccleaner will perform some or all of the following activities:

Scan registry for unwanted / malicious entries
Remove unwanted / malicious entries to combat registry bloat
Remove or replace obsolete files
Back up the registry
Remove incorrect file and program associations
Recover the registry if any maintenance task fails
Defragment the registry to remove any free spaces
Repair or remove system files such as unused or shared files DLL files find no longer needed device drivers and old ActiveX files
Schedule a scan to make sure the registry is scanned and errors are automatically repaired.

Many third-party registry cleaning utilities remove unnecessary bloat and keys that are no longer relevant to the current system, and then defragment the registry files.

Resetting is one of the system recovery options in Windows 8.1. It is advisable to use this function:

if you wish to delete all of your data and restore the state of your computer at the time of purchase;
when the computer cannot be restored in any other way.

What is the difference between resetting and reinstalling

It differs in that you do not need to reinstall the drivers and enter serial number product. The recovery program will only fix problems in the system kernel and delete personal files.

How to return Windows to its original state

Boot from the installation Windows disk 8.1:

In the window Installing Windows click Further:

Select item Diagnostics:

Please select Return to original state:

In most cases, this list will only have one copy of the operating system. If there are several of them, select the desired (or problematic) system that you want to restore:

At this stage, you have a choice: 1) clean only the system partition; This option will suit you if your OS has become unusable and you want to restore it for further use. For a complete recovery, it is enough to restore only the system partition. 2) clean up all disks on your computer, if you have more than one. This option is suitable in cases when you want to sell your computer and clear all data. Also, this option is desirable if you are recovering the system after a virus infection and have already saved all important documents to a USB flash drive.

In most cases, the option Just delete my files... This will give you a chance to recover some files. If you select the second item, the system will completely erase files to protect against recovery. This option will take much longer and is suitable if you are selling or donating your old computer.

Click the button Return to original state to start the Windows restore process to its original state:

After that, wait until the progress reaches 100% and the system will restore its original state:

After resetting the operating system, the computer will behave as if you just installed on it operating system(well, or as if you just brought home new computer with Windows 8.1 preinstalled). Select your region, language, time zone and keyboard layout:
