When you have many WSUS-servers with central server in your organization, it might be very difficult of getting reports from computers.
Once I needed a script to show me, at which computers I don't have approved updates installed. There is a report in WSUS console that can give such info (it's called Computer Tabular Status for Approved Updates), but I was not able to go to every WSUS-server and run this report. Its a very weird task when you have 5-10-15 of WSUS-servers.
