Windows 7: Checksum problem Windows 7

Checksum problem Windows 7

Hello all.

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

what's your SHA-1 checksum ?

I can compare them with versions on technet ?

Why would that be if both were made under Windows and both in the ISO format?

Also, can anyone post here the size of their ISO image?

none of the numbers for versions on technet look like yours but if you google 00def0020d1b0648ed2dc3a89b2cd275da176448 i get lots of hits for Win7.ULTIMATE.retail_House.party and Windows 7 Ultimate Signature Edition x64-ENG

cant find anything official from Microsoft though

my en_windows_7_professional_x64_dvd_x15-65805 is 3.0gb

and my en_windows_7_ultimate_x64_dvd_x15-65922 is also 3.0gb

This is what is puzzling me. I am so used to verifying checksums that I find it weird now to install it without them matching the ones on the Technet site.

It can't get any more reputable than this. I got a DHL Priority all the way from Redmond itself. I may be sounding too obnoxious, but something feels missing since there is no match for my SHA1 and the only places there is: on warez sites!

If you got it directly from MS, then what is your concern?? Install it and enjoy Windows 7..
