Once again today the MS Techs assured me that a clean install is possible and there are NO upgrade DVDs available.
So this is 2 different techs-weird.
Anyway,as I said above all is well, just wanted to mention a feature I found also that's great.
Built in Recimg.exe command line.What you do is make an image and that image, when placed where the info tells you becomes your "refresh my PC" backup like Joeb mentions above.
Now that is cool. IMHO(I can post the steps or you can google the exe)
