Just bought a used business computer. Windows 7 Professional is not installed but there is a Product Key on the COA sticker that came with the computer. If I install Windows 7 Professional can I use the Product Key on the sticker to activate this installation with Microsoft?

50/50 maybe they've already reused that key elsewhere maybe not. I'd certainly try before I bought a licence. Only thing that can happen is it tell you the code is in use.
