I have a question about managing RDSH-servers with App Volumes. In my environment, I've noticed that when I have Appstacks attached to a RDSH-server and I want to install Windows Updates or updates to the applications which are installed locally, those updates are not installed anymore after a reboot. It looks as if App Volumes "captures" the changes to the OS and as the attached Appstacks are read-only, those changes are discarded after a reboot. See: http://svenhuisman.com/2015/05/disable-app-volumes-service-before-updating-os-or-installed-apps/

My question is: Is this expected behaviour and what is the best way to manage the RDSH-servers? Do you need to disable the App Volumes service before making changes to the OS?
