ConfigMgr 1511 is a great Win10 management tool, and so far the only real enterprise management tool I have seen when it comes to deploying Win 10 1511. There is a minor UI issue that might make you freak out. When downloading the upgrade our Download Software Updates Wizard is not really moving although everything runs smoothly in the background.
The trick is to open Patchdownloader.log - if you can find it – it’s located in %temp% if you started the download directly from the server. Notice that the log file is updating like a charm.
