I'm following these steps to deploy "Upgrade to Windows 10 Enterprise, version 1511, 10586 - en-us, Volume" to a PC running build 10240. I am able to deploy to Software Center and we receive the prompt to restart after installation, however the PC does not kick off the upgrade process after rebooting. Instead it returns to the login screen. Opening Software Center after this reboot shows that the update status is "Installed", which is all the more baffling. I'm not sure why this upgrade is not starting. Attached is a screenshot of Software Center and our UpdatesStore.log file. UpdatesStore.log
