My SSD is breaking down and I intend to refund it. My OS is on the SSD. Can I install my Win7 OEM-version on my HDD for the time being and then again install it on the new SSD when I get it? I heard that the OEM-version locks on the MOBO. So, as long as the same MOBO is plugged into whatever memory device, I can install this Win7 on it however many times I want? Or did the OEM-version only have one installation?
Your copy of Windows is locked to the PC on which you purchased it. You cannot transfer that license to another PC. You can upgrade any components or peripherals on your PC and keep your license intact. You can replace the motherboard with an identical model or an equivalent model from the OEM if it fails. However, if you personally replace or upgrade the motherboard, your OEM Windows license is null and void.
