Removing Windows Updates (KB-articles)

Ouch, ever been in need of removing an Windows update? Usually this is often done when a particular update is interfering with an internal application, and normally this can be achieved with the wusa.exe tool:

WUSA.exe /uninstall /kb:2863908

But this has proven only to be working if the KB is related to Windows, else you will be getting this error: The update is not installed on this computer.

The correct answer to get rid of the update (besides uninstalling it manually) lies within the registry. Searching for the KB in question will give you a key named UninstallString with a value equal to this:

“C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE15\Oarpmany.exe” /removereleaseinpatch “{90150000-0011-0000-0000-0000000FF1CE}” “{6764E50D-D076-41BC-B069-08DD488AE88B}” “1033” “0”

Running this command directly will also remove the mentioned update, but will require manual intervention (we don’t like to do stuff manually)

However, you can use these values with the Windows Installer: msiexec.exe:

msiexec.exe /package {90150000-012B-0409-0000-0000000FF1CE} MSIPATCHREMOVE={6764E50D-D076-41BC-B069-08DD488AE88B}

Enjoy 🙂
