Ok that's way more than I ever expected xD Nice! I don't think I ever did an in-place update. I just love the feeling of a completely new install with no left overs ;P

That's actually a very good point now that you mentioned it. I didn't consider that and assumed that an ASP.Net app would be large enough to see some optimizations but I guess the libraries used are already optimized and my code doesn't have much stuff to optimize.
