My desktop runs windows vista at the moment (not out of choice). It has some windows specific software I need so I can't change it to linux but I can get a cheap upgrade to windows 7.
However it's for a limited time and if I don't do it before I go home on the 19th I won't be able to by the time I get back to Uni. So what I am looking for is some important information quickly. How well does the computer tend to operate after an upgrade (instead of a full reinstall). How long does it take to do? How easy is it? I need this help pretty quickly too.
