Fortunately SoCal we aren't constrained by the American way of doing things where corporate policy tends to supersede law on a regular basis and he with the most expensive lawyer wins.
The 1991 EU Computer Software Directive very clearly and specifically nullifies a software vendor's right to control the resale and redistribution of software after initial sale. Therefore, MS can write what the hell they like in their ridiculous EULAs but it's legally unenforcible. In the EU it is 100% legal to resell any piece of software no matter what nonsense license the vendor attaches to it.
