WSUS: Save Disk Space (Purge Unused Updates)

To save space on your WSUS server, you can purge unused updates. There’s no need to keep old updates that are no longer useful.

For this, you need to use the “WSUSDebug” tool (available here for direct download or here).

Download and install it in “C:\Windows”. Then open the command prompt and type:

  WsusDebugTool.exe /Tool:PurgeUnneededFiles
wsusutil.exe deleteunneededrevisions
WSUSUTIL.exe Reset
WSUSUTIL.exe Removeinactiveapprovals
