I got one through my school for $34 and now I'm wondering how do I install windows again if I want to reformat or even upgrade? The key is only good for one computer... How does the software check?
Oh, I have windows 7 64bit on my computer right now and runs great. I was asking if I decided to do a full computer upgrade next year, how do I get the same activation on that computer transfered?
What I am asking is do I have to deactivate my key in order to reactivate it on another computer?
If the purchase was a Windows 7 Upgrade pack then it depends upon what you use as a qualifying license whether or not you end up with an OEM or a retail licensed install. Upgrade a previous retail license and you end up with full retail license entitlements. Upgrade an OEM license and you inherit the legal restrictions of the previous OEM license.
