For such a registry backup to work in Windows 10 1803,1809,1903,1909,2004 and newer Windows 10 builds, you need to manually turn on automatic registry backup through the special reg parameter (this must be done beforehand before problems with the registry appear).

If these commands did not fix your problem, you need to restore the registry from the last restore point or registry files backup.

Open a command prompt as an administrator and run the command: sfc /scannow It is recommended to use the Dism.exe and Sfc.exe command-line tools to check the integrity of system files (including registry files), and fix the errors.
