I have a Dell laptop in front of me running Windows 7. the main problem is that when I click "computer" from the start menu trying to find a file on the (C:) drive Windows Explorer crashes. Also these computers are in a domain. When the person who uses this computer daily logs in, windows explorer crashes and loops. So I ran a virus scan and malware scan and neither produced significant results. So then I ran SFC /Scan in the command prompt and it looks like there are some damaged .dll files. I'm stuck here. I'm not sure what to do next. I have posted the sfc details below.

There were a very good amount of files that were repaired but below are the oddball weird ones that showed up in the list.

  • If the source file in the store is corrupt, provide the SFC tool, a different source store. In other words download a Windows 7 .ISO, extract the install.wim image, then point SFC to that extract image. Honestly though given the amount of corruption I have serious doubts you will be able to accomplish that, so it might just be best, to cut your loses and install a fresh instance of Windows 7 again. I would put money that your system drive is about to completely fail on you.

  • Those specific files are not even in the WinSxS what I suggest would only fix hose that are. WindowsCodecs.dll belongs to some other package that you have to install manually.

Run regedit.exe, go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\ComponentDetect\amd64_microsoft-windows-windowscodec_31bf3856ad364e35_0.0.0.0_none_167a48aba1a5cb67

and on the right side you see some text. Look here for the version 7.1.7601.18135 ad look under Name which KB number you see in the text "Package_for_KBxxxxxx". Now use control panel to uninstall the update with this KB number.

If this doesn't work and removing also fails, do the following. Download the MSU file for this KB from the downloadcenter, put the MSU into the folder %SYSTEMROOT%\CheckSUR\packages and run the checksur tool KB947821.
