Show more detail when installing updates during shutdown/reboot
Installing a Windows Server 2016 cumulative update (e.g. after setting up a new server) can take pretty long. After a few minutes, the unchanging message "Getting Windows ready / Don't turn off your computer", despite its looping dots, stops inspiring confidence that progress is being made.
Monitoring %windir%\Logs\CBS\CBS.log helps slightly, at least until "CommitPackagesState: Started persisting state of packages".
I would therefore request that
* on Windows Server, and optionally on Windows 10 as a configurable option, the "Getting Windows ready" screen shows additional detail, similar to the output in CBS.log (e.g. "processing package 1564/7144 for KB4025339")
* if possible, CBS's persisting of packages be logged more verbosely to make progress more obvious
