How to fix a corrupt user profile in Windows 7 and Vista: The User Profile Service failed the logon

by on Feb.16, 2014, under Windows

I had a recent issue with someones laptop where I got the

The User Profile Service failed the logon

for a Vista installation. This is the second time this has happened on the same computer.
The first time I recreated the user and copied the data across and repair installed windows.

This time I used the reference below. I had 2 entries for the user under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList, the second one having a .bak suffix. The first one was also brief containing only 2 entries and missing the rest.

So I:

  • renamed the original to a new suffix (just in case)
  • removed the .bak from the other one
  • and set state to 0 (was 0x8000)

Rebooted and voila login worked again.

This is here for my fast reference. YMMV
