Note regarding buying an OEM license: Don't buy one of those $5 specials on eBay which offer a serial key and/or an installation disc. Those have already had that serial key activated on someone else's machine, and the all-important holographic validation sticker is on that guy's computer. Those offers are worthless.

You want the unopened CD envelope with the holographic validation sticker inside. They seem to run about $140 now for Win10.
