I dunno, kind of torn on the upgrading microsoft part.
I do upgrade my windows 7 professional 64bit pc's here at home,
but I have one that I kept XP on, and NEVER let it do ONE update.
It lasted years and years and never had a crash (Dell 8300) and is now running W7 32bit happily...
If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
