When reinstalling Windows 7, does the language, version, architecture (64-bit or 32-bit) or source (OEM, retail, or MSDN) matter?
I had a question about Windows 7 licenses. Say I use mine, but later on I need to run a system recovery or reinstall the OS, will that same license still be usable, or do I have to purchase a new one? Also, I have an HP laptop. If, after I install Windows 7, I call and ask them for a Windows 7 recovery dsc, would they give me one, or would they refuse since Vista was the default OS?
Thanks for your help!
OEM licenses are bound to the first computer they're installed on. You can re-install as many times as you want but you cannot move the license to another computer.
