Quite often in Windows-systems you can observe the appearance of errors associated with damage or lack of important system components that are extremely important for the operation of the OS. If system files are deleted by mistake of the user or as a result of exposure to viruses and malicious codes, cardinal methods may be required to restore them. Do not rush to reinstall the system. This method is only suitable if none of the solutions below help.
Checking the integrity of system files in Windows 10: basic directions of action
The Windows family has undergone many changes as it evolved - if you want, systems have become smarter. For the first time , health recovery was applied in the Millennium version. Then the decision was to create a backup from which it was possible to make a download. However, this option might not always work.
Today, recovery of Windows 10 system files after verification can be done in several ways. This mainly concerns the use of the command console. However, the standard rollback option is also not excluded (naturally, provided that the user did not delete the saved control points).
Restoring Windows 10 system files with the simplest method
First, consider a situation where the system does not boot due to critical errors. In this case, in theory, recovery can start automatically. If this does not happen, you should force restart the desktop computer or laptop several times using a long press of the power button.
If the system displays a message stating that recovery is not possible, you will have to use the manual selection of loading the last successful configuration. But only in the tenth modification of the system, pressing the F8 button at the start of loading to call up the additional menu, as it was in earlier versions, does not work. Therefore, you will have to boot from the installation disk or flash drive with the transition to the recovery console, and only then choose to start the corresponding mode.
However, you can return to the standard setting in a completely elementary way by calling the command line and writing in it such a combination: bcdedit / set {current} bootmenupolicy legacy. After that, when restarting, you can use the F8 key to call up an alternative boot menu.
Secure boot and reset
It is possible that the Windows system files have not undergone critical changes, and the computer system can be loaded in safe mode by selecting it from the menu described above.
Here you will need to go to the settings, select the update and security section, and then use the reset button in the restore item. By the way, you can also use special boot options in the same place to get access to additional start parameters if the F8 key is not provided. In the start menu, the system boot points and the transition to recovery tools will appear. As already clear, the integrity check of system files in Windows 10 will be made by scanning a backup copy of the system itself and the registry. By and large, if the user suggests that problems may arise on the computer, a copy of the system registry can be created in advance using the export function in the corresponding editor.
Using a special recovery command
But the universal tool is still considered the command console, which is used to eliminate most of the problems and critical errors.
In particular, the sfc / scannow command allows you to perform a full scan of all system elements, and if problems are found, restore them. In this case, it does not matter from which device the download is made. The sfc / scannow command works both when starting from a hard drive and when booting from removable media. But in the first case, a prerequisite is to run the command console as an administrator.
Online recovery
No less effective is the online recovery tool DISM.exe. To run it on a computer, access to the Internet must be active. There are two options for using the DISM.exe tool.
On the one hand, sometimes only the recovery line, which is shown in the image above, is enough. If an error is issued, you will first need to enter the scan command "health" of the computer. In any case, the correction will take place.
Missing Library Download Issues
If anyone does not know, the system files of the operating system include a large number of dynamic libraries. Their damage or removal can also lead to the fact that the OS will start with violations.
In this situation, you can use the DLL Suite utility, which provides for checking the integrity of the Windows 10 system files or any other system, after which the missing or damaged components will be loaded. Again, its use implies access to the Internet. The disadvantage of this application is that it can only be used in an OS that is somehow loaded (for example, in safe mode).
Using fixers
There is another category of tools that are commonly called fixers (means of eliminating errors). The most famous “native” utility developed by Microsoft specialists is Fix It !, which, however, also works exclusively on a bootable system. And it is far from a fact that problems with system files will be fixed. The program can easily report that they are found, and their correction by automatic means is impossible (the user will have to do this on his own).
If you need to boot from removable media, followed by verification and recovery, it seems much more appropriate to use the appropriate applications from Acronis. Fortunately, you can find a lot of them.
Now a few words about the situation when checking the integrity of the Windows 10 system files revealed corruption at the boot record level. Here, except for a special tool of the OS itself, nothing will help. This is the executable file Bootrec.exe, launched through the command console, for which you need to enter additional parameters and attributes: “/ FixMBR” and “/ FixBoot” (without quotes).
If recovering the bootloader using this method is not possible, the complete rewrite command “Bootrec.exe / RebuildBCD” can really help. But this tool works almost always (with rare exceptions, when viruses are firmly established in the system).
Conclusion
To summarize, it can be noted that the application of each of the above methods to restore Windows 10, if the problems are precisely the damage to system files and components, depends entirely on the situation. In some cases, a normal rollback helps, sometimes tools work with a command line, in some cases, loading of deleted or damaged components works. Online recovery does not always work. At least if the system can be booted safely with network driver support, there will be no problem. In the event of a start from removable media, no one will give an Internet connection guarantee. However, you can try all the methods. Perhaps at least one of them will help. It is clear, after all, that this will save the user from the need to reinstall the OS (and this process is quite lengthy, since during installation it may be necessary to download updates, which may take several hours). Yes, and installed user programs will be deleted. Therefore, before making such a cardinal decision, you should first try out the methods described above.
However, the solutions used are not dogma. And it is not necessary to follow them in the exact order in which they were described. It is likely that the command console toolkit will give an immediate result (by the way, it is most often used). But the use of other methods cannot be ruled out. You never know what ...
