I recently installed an automatic upgrade and now I'm getting "The User Profile Service service failed the logon. User profile cannot be loaded" when I turn on the computer. My only option is to click on an OK key. The computer then gives one logon key and when I click on it give me the USER PROFILE CANNOT BE LOADED message again. Only options given with logon key are improve use of screen and restart, sleep, hibernate, and shut down key. It will not let me start in safe mode and will not give me access to the START button. I've tried every option available to me; even tried ctrl/alt/delete with no success. PLEASE HELP!
