The license is per machine.Darth Servo wrote:I was under the impression that the copyright was for one user, not one computer and said one user could load it on as many of his own machines as he wanted. Guess I was wrong?
OEM licenses are tied to the machine that they were originally installed on.
The machine dies, that license dies.
Though if you build your own machine and buy an OEM copy from Newegg or somewhere and later replace the mobo, supposedly you can call MS and they'll reactivate it for you.
Retail copies (full install or upgrade) aren't limited to the machine that they were first installed on (though you're still limited to it being on only one machine at a time), so if you upgrade a lot, buying a retail copy makes more sense than an OEM copy.
My own copy is an Upgrade disc that I use an old copy of Win98 as proof of eligibility.
I run the XP install disc and when it asks for proof of eligibility, I pop in the 98 CD, it checks to see if it's a valid CD and then I remove the 98 disc and put the XP install CD back in and proceed from there as if it were a full install disc.
