Stop applications reopen automatically after an update is applied by SCCM
Reopening after restarting Windows...
After the computer receives Windows Update via SCCM, the computer restarts normally and after the user redo Logon, it automatically reopens the software, such as Paint, Calculator, Google Chrome, Internet Explorer, etc.
This is a feature of windows, and SCCM will not overrule this feature. It is the way many people desire updates to work, that it is invisible to them that windows was updated while they were away.
