Automate process of Disk Cleanup cleanmgr.exe without user intervention
The following Powershell script automates CleanMgr.exe. In this case, it removes temporary files and runs the Update Cleanup extension to purge superseded Service Pack Backup files (Windows 10 now does this automatically via a scheduled task). To automate other extensions, create a "StateFlags0001" property in the corresponding Registry key, as done in the New-ItemProperty lines. You will find the Registry key names in the "VolumeCaches" branch.
As far as being silent, this script attempts to start CleanMgr.exe in a hidden window. However, at some point CleanMgr spawns new processes which are visible and must be waited on separately.

You can use cleanmgr /verylowdisk to silently automate all the cleanup steps.
The only solution I found is to manually set the registry values like this:
