Hey everyone. I am wanting to buy Windows 7 Professional 64bit edition from software4students. They only do upgrade editions from xp and vista and Im currently on windows 7 home premium 32 bit. I was wondering could I just install xp from an old disk quickly onto the harddrive and then use the upgrade disc? Thanks.

Just run it and go through all the stages. I did it with my Windows 7 Pro edition. I don't think it complains either :S You are technically upgrading your machine from Home Premium to Professional. It's only tricky when installing on a fresh, OS-less computer where you install it twice - Once for the OS, and twice because it discovers it's not an upgrade but with the second run it thinks you're upgrading.
