Uninstall Windows updates from the command line.
From the System Recovery Command Prompt run the following command:

  • dism /online /get-packages

This will produce a list of installed updates and packages. They will look like this:

           State: Installed

           Release Type: Security Update

           Install Time: 2/11/2010 1:01 PM

Find the most recent one and then make a note of the package identity.

Then run the following command:

  • dism /online /remove-package /PackageName:Package_for_KB978262~31bf3856ad364e35~x86~~6.1.1.0

           Note: Name of update is from previous step which may vary.

You will get a status of the removal until it is complete. Then reboot your PC.

You will want to start with the most recent and remove them one at a time to find the problem update.
