How to fix a corrupted profile on windows

If you encounter a corrupted user profile on Windows, you can follow these steps to fix it:

1. Sign in with the local account
2. Open Regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
3. Find the profile keys with the same matching numbers, Example :

S-1-5-21 123456-123456-123456  (The new one .Temp)
S-1-5-21 123456-123456-123456.bak (The .bak is supposed to be the original before the profile corruption)

4. Rename the new key without the extension to .bak1
   S-1-5-21 123456-123456-123456 (The new one .Temp) to S-1-5-21 123456-123456-123456.bak1
5. Remove the extension .bak from the original profile S-1-5-21 123456-123456-123456.bak to S-1-5-21 123456-123456-123456

6. Reboot the machine
