Are you serious?

It's bad enough that windows update "sometimes" (ie usually) requires a reboot. Its unacceptable that it "sometimes" (ie frequently) does a reboot, even though you've told it not to reboot and/or that it persistently nags you if you persistently say NO NOT YET and then does it the moment you turn your back, despite the fact there are important jobs running which can't be interrupted.

However, multiple reboots -- that's just plain STUPIDER THAN STUPID and INCOMPETENTER THAN INCOMPENTENT.

I'll say this just once.

BILL GATES, ITS HIGH TIME YOU RESIGNED AND WERE REPLACED BY SOMEBODY THAT UNDERSTANDS HOW TO DESIGN MAINTAINABLE SYSTEMS THAT *D*O*N*T* NEED REBOOTING EVERY FIVE MINUTES, or better still don't require rebooting at all -- and above all, never ever without the user's permission.

Did you hear that ? Well, did you?

And if you don't understand WHY the above is necessary, then its definitely high time you went.
