Windows will automatically create a temporary profile when a profile becomes corrupted so you will need to delete this profile so you can log back in with the original profile.

In regedit make your way to

to "KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList"

The profile key ending in bak highlighted Blue is the original profile.

Delete the one above this highlighted Red named the same but without the .bak extension.

Now remove the ".bak" from the bottom key.

This will allow your computer to reboot using the correct user profile.
