Windows 7 - MSDN AA MD5 Hashes

Recently I have been having a problem with my Windows 7 ISOs and installations. Windows 7 will not install properly to my system. I have tried all of the "check your memory for corruption" as well as the "burn the ISO at a very slow rate" routines, but with no success. Typically I install Windows 7 from my thumb drive anyway because its probably 5x to 10x faster than by DVD. Also, I use the MSDN (Academic Alliance) images.

Just recently I checked the MD5 checksum of the image I was using to install Windows 7 and found that it did not match the MD5 checksum of the newly downloaded image direct from Microsoft's MSDN servers. Here are the MD5 checksums of the new images as well as the original image file names for reference.

I really hope that this information will help anyone with a Windows 7 installation error. This should probably only be used in the case of an MSDN image installation though because I have not checked the RTM/OEM or retail images to see if any are the same.

Thanks a bunch for this post. I spent an entire weekend and a shitload of blank DVDs to burn faulty MSDNAA ISO images. I eventually downloaded a Windows 7 torrent and used my MSDNAA licence key with it. Luckily, I got the right version (otherwise I figure my key would not have worked).

By the way, I was wondering. Is there a place where Microsoft states (black-on-white) what the MD5 sums for all the stuff they post on MSDNAA are? Because their crappy downloader surely doesn't do its job right (it just downloads, without bothering to check the integrity of the file).
