Not really, but I wouldn't waste money with buying a Windows key even at like $25 for that PC.one follow up question in general, if I install a new os on a computer, I need to pick an os that came out around the time computer was made or an earlier os version to make sure it will run on computer, and if there is a product key on back of computer, I need to install the same os listed on product key or make sure the os comes with it's own product key. Is all this correct?
