How to fix User Profiles in Vista and Windows 7

NOTE : This does not ALWAYS work.


My boss just arrived in the office saying that her ‘User Profile’ is corrupt. I am usually ‘hot’ on fixing these problems easily so thought I would share the best solution – from my experience.

<code>The user profile service service failed the login. User profile cannot be loaded. </code>

Check the following registry entries (you will need another User Profile to be able to log in with Admin priviledges) with REGEDIT under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

There was 1 line for each profile.

Crucially if a profile is bad there are 3 things worth checking

1) Ensure the key name doesn’t end in “.bad”

2) Ensure the RefCount value is 0

3) Ensure the State value is 0

Having done the above, the profile then usually works fine, if this doesn’t work for you, but you found another way – please post a comment and it will be added so that others can benefit from our misfortunes.
