Yeah, I'm still up ... Forgot to say that since MS Security Essentials won't update its virus definitions, which typically takes only a minute or two, then seems the whole Window's Update functionality is broken. That's why I don't think letting Window's Update run for a super long amount of time is going to make it complete the task since MSE can't update either.
