Is Windows.old directory automatically removed?

We are preparing OS upgrade from 1709 to 1809 for >5000 workstations.

After upgrade Windows.old takes between 5-10 GB of disk space.

 

In the MS doc is stated you can use DISM /Set-OsUninstallWindow to defile how long user can roll back.

But after this period (default=30 days), does Windows also *automatically* clean up Windows.old?

After 10 days , that folder automatically removed, but after then that folder exists, you can use other method described below link.
