Released: September 2016 Quarterly Exchange Updates

Currently testing Ex2016 on Windows Server 2016. Found an issue when uninstalling Exchange. Looks like at some point we get an Access Denied error when unregistering one or more DLLs. Uninstallation is done remotely using DSC and running with proper credentials. Issue doesn't occur when using Windows Server 2012 R2.

Also tried uninstalling from an interactive session, same issue. Of course, I have proper privileges on the server.
