"configuring updates 3 of 3. 0% complete" reboot loop in Vista - possible fix

Instead of tacking yourself on to an existing thread, try starting a new one
with OS, service pack and error code/codes you are receiving. You may think
you're having the same problem, but different OS's may have different fixes.

Have you read the complete thread and tried any of the previous fixes listed
in TaurArian's reply?

It's a well known fact that most people who are helped here don't respond
back with a "thank you" or "it worked."

Try dropping the attitude. No one here works for Microsoft. The MVP's are
volunteers as are all the others who try to help.
