windows - Extracting a file from the WinSxS folder


Specifically, I'd like to get the file explorer.exe of version 6.3.9600.17238 (from Windows 8.1 Update 1). I have the following file on my system:


C:\Windows\WinSxS\wow64_microsoft-windows-explorer_31bf3856ad364e35_6.3.9600.17238_none_4d01a98581e82d4f\explorer.exe

But it looks like some kind of diff, it's only 216 KB, while the original file is around 2 MB.


How can I extract the file? Or alternatively, is there another location where I can find this file, locally or online?


I need the file of this specific version for a tool I'm developing. Not in order to repair an OS installation.


Answer



The Explorer.exe in version 6.3.9600.17238 is part of the August 2014 Update Rollup for Windows 8.1.


You can use the Windows inbox tool expand.exe to expand the MSU and next the CAB file to extract the Explorer.exe:


expand -F:* Windows8.1-KB2975719-x64.msu C:
cd
expand -F:* Windows8.1-KB2975719-x64.cab C:
