Preparing To Configure

So there I was, running Windows Update on bunch of computers at work like I do every month and on the final computer something goes awry, on the console there's an innocent "preparing to configure, do not turn off your computer" message.. so what's the big deal? you might ask, well .. this one wasn't going away. I waited few minutes, then some more and when I had waited for something like 10-15 minutes I felt my stomach cramp up (since that's forever in my perspective since I have horrible luck restarting physical machines, they tend to die on me). Something just had to go wrong on the last one .. and here I was looking forward to going home, start my extended weekend and catch up on some sleep.
