Quick background.. I bought a pro (retail) key online, and the seller said it was a unique key. I have no way of knowing if that's true or not, and it would not surprise me to learn the guy is reselling the same key. If I activate Win7 with my key online, and other people get the key and try to use it, will my windows automatically deactivate? Obviously it's 1 key = 1 computer, so I assume my Windows install is no longer "genuine", but will my install magically deactivate, or could I just not allow MS to verify my OS once more (like not allowing that Genuine Software program from MS run)? Also, I read in the FAQ I can use my retail key with an OEM disc (and vice-versa) but in order to do so, do I need to modify the .ini or .cfg file to say 'retail' channel vs 'OEM' channel, or will the install program figure it out? The OEM is already professional, so no change in the actual "version" of Windows. Thanks guys!
