Hi friends, i have installed "Home Premium" some days ago and now thinking about it, to install the "Professional" Edition of Windows 7. I want to use Virtual XP, that isn´t supported by Home Premium.... ;-( My question is now.... Is it possible to upgrade HP to Pro with Anytime Upgrade? Is there a place where i can obtain an upgrade key? Or do i have to do a clean reinstall of Professional? Sorry for the noob asking..... Thanks for your replies!
