I just got a promotional copy of the Windows 7 Ultimate x64, under the New Efficiency Program. I am a Microsoft Student Partner.
I just verified the md5 and sha1 of the ISO file I created, and they don't check out with the versions on the MSDN site, since the code is different. The DVD I got is akin to that distributed under the Windows 7 Launch Party program.
My question is, if the promotional DVD has the same content as the Retail one, why are there different checksums for them? Is there any difference between the promotional and the retail versions or what?
I know I shouldn't be picky since I got this DVD directly from MS, but I am used to verifying checksums and if they don't match, it feels weird
