The Security Mentor

Are you doing everything right?

Are you logging in as someone without administrator privileges? Good, you should. Are you using the Run As feature (shift-right click on a program) to run things like Windows Update that actually need administrator privileges? Good, you should.

Unfortunately that doesn't work with Windows Update any more. You need to log off from your regular account and login again as an administrator to run the new Windows Update. Why would Microsoft break something that useful, especially when they've been pushing people to log in with limited rights? Because Microsoft is a big place and the left hand doesn't always get the memo from the right hand.

If you're getting a completely information-free error message from Windows Update try logging off and logging back in to an administrator account.
