My computer came with a copy of Windows 7 Home Premium. If I upgrade it to Windows 7 Professional, what will happen to Media Center? Will it be deleted because it's not available in Professional, or will it be kept because I also have a license for Home Premium? (or just because it was already on there)
Windows 7 "Anytime" Upgrade is the easiest least expensive way to upgrade, be sure to keep your anytime upgrade key somewhere safe.
