  If you are using WSUS in your environment, you may want to run a scheduled task to cleanup old updates and compress some of the larger updates to free up space on your server. A good way of doing this is to run a Powershell script which will take care of all your cleanup requirements and as we are using Powershell, we can even get it to send us an email once it is complete with the output information on what the script has managed to clean up.

This makes the much easier to use the output as the basis for a template object or as the payload body to create an object in another tenant.
