Hello Trevor, Thank you for your reply and for the link.
However, in my case all my workstations are x64 systems ( we don`t use x86) I used SCCM 2012 R2 to deploy all Office updates. Now... if you try to uninstall a KB using the simplest command: C:\Windows\System32\wusa.exe /uninstall /kb:2850061 /quiet /norestart /log It will failed with: “ Windows Update could not be uninstalled because of error 2359303” I also tried to use: C:\Windows\SysWOW64\wusa.exe /uninstall /kb:2850061 /quiet /norestart /log Failed with “Windows update could not be uninstalled because of error 2147549183 "Catastrophic failure" (Command line: "wusa.exe /uninstall /kb:2850061 /quiet /norestart /log")” I also tried C:\Windows\System32\wusa.exe /uninstall /kb:2850061 and guess what: “The update KB2850061 is not installed in this computer” Well it is ! because I can see it in my Programs and Features – View Installed Updates... I finally come across this: https://cms.arstechnica.com/civis/viewtopic.php?f=15&t=1217819 It seems you need to use DISM: dism /online /get-packages /format:table > patches.txt Unfortunatelly in my patches.txt list I cannot find KB2850061 which is an Office Update ( only Windows updates are listed) Any ideas ? Cheers. Bogdan.

I found this article ( Last Review: February 21, 2014 ) http://support.microsoft.com/kb/2934750 Using more then 1000 clients, I choose Method 4: Revert to an earlier version of Outlook; Basically they say: “If you have an MSI installation of Office 2013, you can try to uninstall the October 16, 2013 (KB 2825677) and December 10, 2013 (KB 2825652) hotfix packages for Outlook 2013.” KB2825677 is a .msp file KB2825652 is a .msu file I know the command for installing both, but I`m not sure about uninstalling the .msp file, is this okay ? msiexec /uninstall Update.msp /quiet /norestart What is the best method to include both in Task Sequence ? Thank you. Cheers.
