Actually, the EULA you agreed to (ya know, that legally binding little slip of paper with the sub-microscopic type that slipped past their KrazyGlue Dot Enclosure (trademarks and patents pending) that the dog subsequently ate) upon installation prohibits resale of the product in any size, shape, or form. This is one of the reasons why this site exists, as it amounts to little more than wholesale customer abuse - you're stripped of your "right to resale" (as per the UCC, I could look up subsections if it would make anyone more comfortable).
If you're looking for a temporary Windows-based "fix" to the issue, please visit
a Windows support site. If you're sick of dealing with Microsoft, and wish to embrace one of the many free alternatives - and require some guidance with which distros are compatible with your hardware - feel free to ask here (there's even a list on
the main site).
Otherwise, I'm sure you can find other groups dedicated to bartering Windows for
valuable goods and services (I don't see where the EULA prohibits
that 
) with a modicum of Googling.
