Windows Vista/ 7/8/8.1/10 keep a regular backup of the registry handy in case you need to overwrite a corrupted registry. By default, the RegIdleBackup task runs every 10 days, so that’s as far back as you would lose if you replaced the current registry with the automatically backed-up files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder.


Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

Please type below command into Command Prompt and press Enter key.

Code:

 Dir C:\Windows\System32\config\RegBack

Above command will list files stored within RegBack folder and there file size, make sure files are not zero size if they are do not follow below instructions.



Please replace partition letter C: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

Please type below commands into Command Prompt and for each command you have typed press Enter key.

Code:

Ren  C:\windows\system32\config\SAM         SAM.BAK

Ren  C:\windows\system32\config\SYSTEM      SYSTEM.BAK

Ren  C:\windows\system32\config\SECURITY    SECURITY.BAK

Ren  C:\windows\system32\config\DEFAULT     DEFAULT.BAK

Ren  C:\windows\system32\config\SOFTWARE    SOFTWARE.BAK

 

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\DEFAULT     C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\SOFTWARE    C:\windows\system32\config

This procedure assumes that Windows Vista/7/8/8.1/10 is installed to the C:\ partition. Make sure to replace C:\ drive letter to the appropriate Windows OS installed partition drive letter if it is a different location.


Above commands renames the registry files at their existing location, and then copies the registry files from the RegBack folder to the C:\Windows\System32\Config folder.

If i move my hard disk to another pc will it come up with the same result?

Yes you can use File Explorer (Windows Explorer) from working computer to rename and restore registry hives.

So is this a nice solution?

Will the problem still be there?

It is like you are using System Restore tool to restore registry hives to a date where Windows were working without any problems.

I will try that

Also my pc wont post
