Can a new and unused OEM copy of Windows 7 be installed on a used laptop that used to have an OS but is being sold on Ebay without any OS installed or any key provided?
So long as the OEM version is a true OEM (ie a system builder install) it will install on ANY compatible system. Regardless, M$ don't care what was on the machine before it will not effect it in the slightest if you are doing a fresh install.
Well I am going to buy a used Laptop that's not more than 2 - 4 years old and will be from a major manufacturer such as Dell; is that a good thing in terms of being able to find the proper hardware drivers?
Let me also rephrase or come at my question from a different angle/assumption: if a used laptop had an OS on it before wouldn't Microsoft be aware of that and prevent a new OEM version of another Microsoft OS from being installed on that motherboard/laptop?
