Other than installing the key and doing an online validation I can't think of another way. And doing it that way will burn an activation on a possibly good key. Thanks
What type of key is it? If it is a MAK key then you check it using VAMT 2.0 but if it is a retail key it is impossible to check.
Several MSDN keys. PID checker only seems to check for a theoreticaly real key, not a real but blacklisted key. Occurred after doing an online validation soon after MDL posts about blocked MSDN keys. Passed 971033 up until then. It's no problem for me to test each one online but I don't quite understand the re-arm count issue. After 3 re-arms of a retail key a phone call to MS is required? Thanks.
that does use up an activation even if it is good dude. Good idea but it will waste an activation count on the key. My best advise 91011 is to just install the version of win7 that the keys go to and try to activate. If it does good for you but if not then you will know that the key is blacklisted or just no good. That way if it does activate you will not waste an activation count plus you can use PMR token restore tool to back up the license so you can reactivate at any time without using another activation count. I know for sure that MSDN retail keys have a total of 10 different activations on them(I think technet is the same way) but I think regular retail keys only have 3 activations on each key. MAK have something like 500 activations.
Thanks everybody - ended up installing each version of Win 7 that I had keys for and then testing each key. Came out better than I hoped - about half were good. So it looks like not ALL MSDN keys are blacklisted.
