Information

When you log on to Vista using a temporary profile (user account), you receive this error message: For more information, see: Microsoft Help and Support: KB947215 The User Profile Service failed the logon. User profile cannot be loaded.

NOTE

CAUSE: The jury is still out on the exact cause, but so far : This issue may occur if the user profile was manually deleted by using the command prompt or Windows Explorer by a user or by some program. A profile that is manually deleted does not remove the security identifier (SID) from the user profile list in the registry. Since the SID is still present, Vista will still try to load the profile by using the ProfileImagePath that points to a nonexistent path. Therefore, the profile cannot be loaded. This can also be a issue with the user profile entering into a backup state. Manually renamed the C:\Users\(User Name) folder.

WARNING

If you have this error message below instead, then see: How to Fix the Error "Your user profile was not loaded correctly! You have been logged on with a temporary profile." in Vista Your user profile was not loaded correctly! You have been logged on with a temporary profile. Changes you make to this profile will be lost when you log off. Please see the event log for details or contact your administrator.

Tip

If the steps in the tutorial below do not help or you wish to try this first, then: You can try doing a System Restore to see if it can fix this before using the instruction in the tutorial below. See the related links below for how. If you do not want to repair the user profile, you can delete it and create a new user account in OPTION TWO. If this still does not work for you, then you will be left with doing a clean install for your Upgrade or Full version of Vista.
