I have created a task sequence in SCCM 2012 to uninstall KB3161608 Windows Update. The command line used is C:\Windows\System32\wusa.exe /uninstall /kb:3161608 /quiet /norestart /log
If KB3161608 is installed on the machine that I deploy this to, there are no issues. If the machine doesn't have the KB installed, the user is notified in the system tray "Installation failed", "The software installation was not successful. Click to view the details."
Is there a way to check to see if the Windows KB update is installed before executing the command? If not, is there a way to not notify the user that the installation failed?
