I have worked with this issue several times, especially on inherited servers.   Unfortunately, I have found there is little you can do to increase disk space with regards to WSUS taking up space on the server.   There are many update related files stored in WINsxs folder under the WIndows directory.

If you have Windows Server 2012 R2 you can cleanup the WINsxs folder.   Here is a link with instructions:

Here is the link for Server 2008 R2:

If you have Windows Server 2008 SP2, you can use the Windows Component Cleanup Tool.   You can find this at: Windows Component Clean Tool

Sorry forgot the link for Windows Component:

Run the Clean-up wizard in the WSUS console leaving out the top choice for run 1.

That should clean things up quite a bit.

From there, you can schedule the WSUS Cleanup Wizard to run on a weekly basis.

Worse goes to worst and WSUS can be set to manage updates and not download them leaving that to the endpoints.

That would be OK to do, however pointless. The majority of the patches are already compressed, so compressing again will not gain anything. You might gain a couple of percent, at the expense of slower performance.
