OK, let’s try one trick.

In the “config” folder at C:\Windows\System32\config, locate the current registry hive files …

system
software
security
sam
default

re-name them by appending .old to the filename

In C:\Windows\System32\config\RegBack folder you can find registry backup files:

system
software
security
sam
default

Copy them into C:\Windows\System32\config folder

On completion try a reboot to normal windows.
