I have Windows 7 Home Premium pre-installed on my Toshiba laptop and I have been confused for some time now about Microsoft and their Windows key licensing.
How does it work? If i buy a Windows 8 Pro upgrade and use it on my laptop, is the key binded to it? Or is the key now useless? I reinstall my operating systems basically once or twice a year, will the key have unlimited uses on that machine? Or after a few uses is the key invalid?
Can I do a clean install or only upgrade from an existing Windows installation?
