1] Scan Hard Drive and System files

2] Restore Registry

The problem can be because of Registry files. If it is missing or corrupted, therefore, we need to restore Registry Files in order to fix the issue.

So, launch Command Prompt (as we did in Solution 2) and type the following commands to backup your Registry, in case if something goes wrong.

md tmp

copy c:\windows\system32\config\system c:\windows\tmp\system.bak

copy c:\windows\system32\config\software c:\windows\tmp\software.bak

copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak

copy c:\windows\system32\config\security c:\windows\tmp\security.bak

copy c:\windows\system32\config\default c:\windows\tmp\default.bak

Now, delete the current Registry files.

delete c:\windows\system32\config\system

delete c:\windows\system32\config\software

delete c:\windows\system32\config\sam

delete c:\windows\system32\config\security

delete c:\windows\system32\config\default

Finally, use the following commands to repair Registry files.

copy c:\windows\repair\system c:\windows\system32\config\system

copy c:\windows\repair\software c:\windows\system32\config\software

copy c:\windows\repair\sam c:\windows\system32\config\sam

copy c:\windows\repair\security c:\windows\system32\config\security

copy c:\windows\repair\default c:\windows\system32\config\default

Note: Replace  “C” with the Drive letter in which your OS is stored.

Now, close the Command Prompt and reboot your computer to check if the issue persists.
