The user profile service failed to logon error

[pcandpc]

Got two keys in the Profilelist of the registry that starts with S-1-5 then is followed by some long numbers. Only the one with .bak at the end has profileimagepath of the affected user account. The other one showed something else as it's imagepatch(user/TEMP). To correct the registry should I only delete the .bak that's in the end of one key, or should I swap its name with the other key with the exact same number except without the .bak in the end, which means I'm not only deleting the .bak from the key that has it, but I'm also adding a".bak" to the one key without it?

add .old to the existing one that is the same identifier as the .bak one, then remove only the .bak extension
reboot
