cleaning up WSUS

I have SBS2008. I want to clean up WSUS by removing the updates that have already been applied. This is taking up over 90 Gb of space on the server. How do I go about this?

First, decline the updates that you don't want.
Many will be already declined automatically.
Then download the WSUS Server Debug Tools from the WSUS Page.

You can remove old downloaded updates with "wsusdebugtool.exe /tool:purgeunneededfiles"

Take Control of Web Hosting For Your Clients

As a web developer or IT admin, successfully managing multiple client accounts can be challenging. In this webinar we will look at the tools provided by Media Temple and Plesk to make managing your clients’ hosting easier.

Note for canon:
The wsusutil parameter deleteunneededrevisions  doesn't exist on WSUS 3.1

Instead, the Cleanup Wizard is available from the WSUS console if you want to avoid the download.

Also remove extra languages, producs you don't need etc.

If you have WSUS to only download approved updates that are needed, you should find that the size does not get very big. The database of possible updates can contain thousands without much of an increase in size. So some configuration changes should prevent it from growing unbounded so quickly.
