The User Profile Service service failed the logon. User profile cannot be loaded. error message

I just installed the three latest updates (4/27/11) and now my desktop computer says "The User Profile Service service failed the logon. User profile cannot be loaded." Does anyone have any suggestions. I am using my laptop now because I was the only user on the desktop so there is no way to get on it now.

1st thing to try is a system restore in safe mode to before the problem


Windows Vista

Using the F8 Method:

  1. Restart your computer.
  2. When the computer starts you will see your computer's hardware being listed. When you see this information start to gently tap theF8 key repeatedly until you are presented with theWindows Vista Advanced Boot Options.
  3. Select the Safe Mode option using the arrow keys.
  4. Then press the enter key on your keyboard to boot into Vista Safe Mode.
  5. When Windows starts you will be at a typical logon screen. Logon to your computer and Vista will enter Safe mode.
  6. Do whatever tasks you require, and when you are done, reboot to go back into normal mode.


if that does not fix it read on

read the below tutorial


When you log on to a Windows Vista-based or a Windows 7-based computer by using a temporary profile, you receive the following error message:

The User Profile Service failed the logon. User profile cannot be loaded.


Your user profile was not loaded correctly! You have been logged on with a temporary profile.


If you tried to log on to Windows and received an error message telling you that your user profile might be corrupted, you can try to repair it. You will need to create a new profile, and then copy the files from the existing profile to the new one. You must have at least three user accounts on the computer to complete these steps, including the new account you just created.
