We have installed Office Applications in our Terminal Server which runs Microsoft Windows Server 2012 R2 Standard version 6.3.9600 Build 9600. For some reason, suddenly the Office Applications got uninstalled. When I checked the event logs, it says user is system. I checked the security event logs and no one was logged in at the same time when the Office Applications were uninstalled.
How can it be uninstalled by itself/automatically? Need help.
