Automate process of Disk Cleanup cleanmgr.exe without user intervention

Question

I am developing a powershell script file which shall execute some disk cleanup without user intervention. The user shall not be able to configure anything.

When I run cleanmgr.exe /d c: sageset:1 a popup window appears to select files/folders to be cleaned(cleanup options).

This will create a registry entry containing the settings with the cleanup options and after this, you can run cleanmgr.exe /sagerun:1 which will actually execute the cleanup.

Is there a way to specify the cleanup options directly with powerhell/command line(without the need to manually select things to be deleted)?

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 In this case, it removes temporary files and runs the Update Cleanup extension to purge superseded Service Pack Backup files (Windows 10 now does this automatically via a scheduled task).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.
