Let's talk about the new feature added to the Windows 10 upgrade services first.
In Patch Remedy 18.104.22.168 you have a new checkbox option you can enable. "Elect to copy ISO locally to agent" which tells the installer service to copy the ISO from the network share to the local agents (C) drive before mounting it to extract the files needed to install the updates. We have found through user testing that during large deployments that you may see a location that agents start to have issues using robocopy to copying files from the network if network is slow or many agents tring to grab ISO. This should help resolve some of those kinds of issues.
