Eventviewer was showing Event ID 1515 and I was logged in as with a temporary profile. No other user was experiencing this, so I went about fixing with REGEDIT.

• Open Regedit
• Start > Run > regedit
• Navigate to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\
• Find any profiles with “.bak” in them
• Delete the .bak entire subkey
• Log off, log on
