Yeah, as I said, the correct setup file is actually contained in the dodgy EXE. You can extract it from the dodgy EXE without triggering the virus, seems like the people who packaged this wern't overly intelligent.

ahh well that just sucks !



some people just live to be assclowns


Unfortunately that's true.
Below the specs of the original isos: if the check sums match those of your isos you've got the real stuff - unaltered.

Windows 7 RC 1 Build 7100 Compiled

The build is correct. The rumor is incorrect. The RC build 7100 was leaked and it is the real thing. Here are the CRC32 and SHA1 for the authentic ISO images.

7100.0.090421-1700_x86fre_client_en-us_Retail_Ultimate-GRC1CULFRER_EN_DVD.iso Size: 2.35GB MD5: 8867C13330F56A93944BCD46DCD73590 SHA-1: 7D1F486CA569EFFFFB719CFB48355BB7BF499712 CRC32: E8A1C394

7100.0.090421-1700_x64fre_client_en-us_Retail_Ultimate-GRC1CULXFRER_EN_DVD.iso Size: 3.04GB MD5: 98341af35655137966e382c4feaa282d SHA-1: fc867fe1ab2e0a9796f9e4d155b44ea6998f4874 CRC32: 58fb2be0



PS: You cannot upgrade from any WIN7 Beta release to the RC1 (unless you manipulate some registry keys) and there is a good reason to that. Some new features are not compatible with the beta releases.

You can just edit cversion.ini and it will upgrade fine. No registry key editing. The windows blog had information why this was done.

How can we check our MD5 hash keys?

This thread has me worried now and im sure there might be a few more people who are going to ask how to check as well...

you can try the freeware "universal extractor",
to extract the "dodgy" file from setup.exe.

If the setup.exe on the DVD has a digital signature in its properties then you're fine...

I have attatched an application to this post for you. Put kukubau's MD5 appliccable to your ISO (X86 or X64) into the top box, and then locate your ISO, it will compare the hashes and tell you if there is a mismatch. Note, I still haven't checked the X86 but there are definately a few narked X64 ISO's floating about. However, having scanned the rest of the files, as long as you haven't installed the build by launching setup.exe I believe you should be safe

Odd.... 7100 must not be the RC according to this logic since I upgraded from 7000 to 7100 just fine and all my hashes match the that of the ones for the original iso.

Stuff like this tarnishes torrents' reputation of efficiently distributing large disc images. Obvious solution is to get the torrent header file from a trusted source (for instance, Canonical's servers if you were to get a copy of Ubuntu), but that won't hold with large corporations like MS.

I did run across this same problem in an earlier leaked build. Lesson learned: check to make sure setup.exe has a digital signature intact before burning or copying to a USB drive.

it's only a few days away, might as well just wait to get it from the real source...

Hashes can be easy calculated using the HashTab Explorer plugin. It works fine in any build, including 7100 :cool:
It even gives you a convenient option to compare hashes.

Exactly. Why bother with unofficial when official public release is days away? I won't be wasting my time.

Another good program that I like is hash tab.

Yup my x64 iso checks out according to those hashes. :) Thanks Lord Ba'al

I believe that the "original" ISO actually had an edited file changing the minimum upgradable version

Torrents are a good source, the problem is the idiots that use the hype as a means of transmitting Viruses. Just goes to show that you need to be really careful with anything you download from illegal sources. However I would agree that with leaked builds there is always the danger they can be tampered with, odd that the X86 edition hasn't been targeted
