Windows 7: Extract Files from Windows 7 Installation DVD

Hello Rich. Thank you.

The WinMail.exe file is technically still in Windows 7, but you have to do a few things below first before it will work. However, since Windows Mail is no longer being supported, you would be better off with another email client program like Windows Live Mail instead.

Windows 7 Professional x64

I am running Windows 7 Home Premium x64 with Intel Core 2 Duo processors. A week ago I upgraded my Dell XPSm1710 laptop from 100 GB to 500 GB HD, from 2 to 4 GB RAM. I did a clean install of Windows. Over the past 48 hours, my system has slowed considerably, and downloads are timed-out before completing. I ran the usual maintenance programs, including chkdsk (no problems found), and then a sfc. SFC found corrupt files some of which could not be repaired. I found the report in CBS.log, and it said the following in two locations in the text:

2010-11-06 01:50:31, Info CSI 0000002c Hashes for file member: SystemRoot\WinSxS\amd64_microsoft-windows-autochk_31bf3856ad364e35_6.1.7600.16385_none_3de8def0db722996\autochk.exe do not match actual file [l:22{11}]"autochk.exe" :

Found: {l:32 b:elI/RKVtKUeIfJ+74cDOqymXmfmQsooYFfwkVYni6rw=} Expected: {l:32 b:O9osH5IuxnI1PLLylnIPx189Vzpvz4ebIg63k2Ec+C4=} 2010-11-06 01:50:31, Info CSI 0000002d [SR]

Cannot repair member file [l:22{11}]"autochk.exe" of Microsoft-Windows-Autochk, Version = 6.1.7600.16385, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, hash mismatch

Using 7-Zip, I accessed files on my Win 7 HP DVD. The first part says that the autochk.exe file described in Winsxs above, has a hash mismatch with “actual file {1:22{11}] “autochk.exe””. I take it that the “actual file” refers to the locations of this file in System32 and SysWOW64 folders.

The second part of the CBS report clearly tells me that a hash mismatch file of pA AMD64, [1:22{11}] “autochk.exe”, path/location unspecified, has become corrupted and could not be repaired by sfc.

In the Windows 7 Home Premium install DVD, the following files are found:
  • In Windows\Winsxs\amd64_microsoft-windows-autochk_31bf3856ad364e35_6.1.7600.16385_none_3de8def0db722996\autochk.exe. This autochk file has a date of 7/13/2009 at 7:38 PM, size 760 KB.
  • The Windows\System32\autocheck.exe has a date of 7/13/2009 at 7:38 PM, size 760 KB.
  • The Windows\Winsxs\x86_microsoft-windows-autochk_31bf3856ad364e35_6.1.7600.16385_none_e1ca436d2314b860\autochk.exe has a date of 7/13/2009 at 7:14 PM and a size of 653 KB.
  • The Windows\SysWOW64\autochk.exe has a date of 7/13/2009 at 7:14 PM and a size of 653 KB.

When the CBS report says that the actual autochk.exe file doesn’t match the autochk.exe file in Windows\winsxs\amd64…, which of the files above found on the install DVD would be considered the “actual” file referred to that needs to be replaced? Intuitively, it would seem to me that a file in System32 would be backed up in (and match) the winsxs\x86_..file. Likewise, the SysWOW64 file would be the same as the winsxs\amd64_...file. But this is not the case in the install DVD, where the SysWOW64 file size is 653 KB and the winsxs\amd64 file is 760 KB.

This is confusing. Can you help me determine which of the 4 autochk.exe files on the install DVD I should use to replace whatever it means by the “actual” autochk.exe file?

Hello uvbogden, and welcome to Seven Forums from Vista Forums.

You would want to look in the Details tab for it File version instead in the properties page to see if they are the same.

However, sometimes you may have a newer version in Windows 7 from a Windows Update than on the DVD. In this case, you may not be able to replace it since the version on the DVD is not the same. A system restore might be tried in this case.

Hope this helps,

Question About Which autochk.exe DVD File to Use As Replacement

Hi Shawn,

From the CBS.log file, it indicated that the corrupt autochk.exe file was version 6.1.7600.16385, which is the version on the install DVD. There apparently has not been an update of this file for Windows 7 Home Premium, and I havn't installed the beta Service Pack.

All four autochk.exe files on the install DVD are the same version, 6.1.7600.16385, but with the differing dates, times and size as indicated. Without being certain which file to use as replacement, I copied the DVD file from Windows\winsxs\amd64_... to the same location in my system files. A repeat of sfc now shows no file problems and the laptop is back up and running.

Thanks for the great tutorial. It sure is easier extracting install DVD files from Windows 7 than it was doing the same with Vista. Thanks again for your good works.

Hello Bagavan,

It will vary, so you will need to steps 9 and 10 to determine which <IMAGE INDEX="#"> is for what folder # and edition.
