I know this is kind of a weird post but we have about 700 VDI clients under VMware Horizon View and then 150 physical desktops. All running the same Windows 10 build (1607 LTSB) and running the same Adobe Acrobat Reader DC installed version which was 2018~. All clients were updating just fine until my VDI Clients stopped updating through deployed WSUS updates at the end of 2019. No VDI clients have been updated to 2020 except when I manually applied the update. No auto update enabled, WSUS/ConfigMgr deploys the updates from Ivanti Patch for SCCM.
I am assuming there is some registry key set on physical desktops that is not set on VDI maybe from my group policy but I've looked through gpresults dozens of times and can't figure out what's happening. I attached the ARM logs if they can help anyone... I'm out of ideas here and totally confused as to why this is happening.
