"User Profile Service service failed the logon. User profile cannot be loaded."

Once in awhile you get "The user profile service failed the logon. User profile can not be loaded" error when trying to logon into Windows. This article describes resolution when Default user account is faulty and gives links to other possible causes and resolutions. In my case the error occured when trying to logon to Windows 7 with domain user account that hadn't used that PC before.

Note. I have only experienced this issue with Windows 7 on Windows Server 2008 domain and below instructions have been tested on Windows 7 only (no difference between 32bit and 64bit versions). Same instructions might apply to Windows Vista.

Occasionally, Windows might not read your user profile correctly, such as if your antivirus software is scanning your computer while you try to log on. Before you follow the methods here, try restarting your computer and logging on with your user account again to resolve the issue. If you restart your computer and it does not resolve this issue, use the following methods to resolve this issue. 

Note You must be able to log on to an administrator account to fix your user profile or copy your data to a new account. Before you resolve the issue, log on to Windows by using another account that has administrative permissions, or restart in safe mode to log on with the built-in administrator account. For more information about how to start in safe mode, visit the following Link :
