I am new to SCCM and Patch My PC and just getting started with an eval license after we fired the prior company that provided a standalone product... I am baffled why patching Reader would trigger a reboot. I have never, ever had a need to reboot this after a simple patch. If I install outside of SCCM there is no prompt to reboot from the app. Am I overlooking some setting that needs to be set to stop this behavior?
