1. Find the list of packages installed on the machine with the issue by performing this command

dism /online /get-packages /format:table

for ease of reading I did the following:

dism /online /get-packages /format:table > patches.txt

2. From the list get the Package Identity Name

Package_for_KB2870699~31bf3856ad364e35~amd64~~6.2.1.1

3. Run this command to uninstall the update silently

DISM.exe /Online /Remove-Package /PackageName:Package_for_KB2870699~31bf3856ad364e35~amd64~~6.2.1.1 /quiet /norestart

 

This will run the uninstall without any open windows, and will not prompt for a reboot:

@echo off
wusa /uninstall /kb:2744842 /quiet /norestart
END

If you are manually running the script on a number of computers that you want to reboot after the uninstall, just change the /norestart switch to /forcestart:

@echo off
wusa /uninstall /kb:2744842 /quiet /forcestart
END
