Just downloading windows 7 professional from MS partner site and i was wondering if anyone has attempted an upgrade? and if so how did it go? Reason i ask is my work machine has a LOT of programs installed that i just cant be naff'd reinstalling (or finding again to start with).

So has anyone done an upgrade? i know back in the day it wasnt a good idea, but was wondering if MS had got the whole upgrade process sorted, and considering how closely related vista and 7 is im hopefull.

Failing that im going to dual boot win7 and my old vista partition.
