How to start a disk cleanup on remote computer

If you want to start a disk cleanup with cleanmgr.exe, a sageset needs to exist.
Then following batch first replicates the settings that the command “cleanmgr /sageset:777” with all options selected would have create. After that it executes “cleanmgr /sagerun:777”.
