Hi,
In WSUS, if an update is declined, execute the WSUS server cleanup wizard and check [Expried updates] to clean up the updated installation files in the wizard, and the disk space will be released.
But the updated metadata will not be cleaned up, that is, these updates can still be found in the update view by filtering "Declined + Any".
Hope the above can help you.
Regards,
Yic
