Remove unwanted updates from WSUS to free up some space

I have a server which recently crashed to a lack of space on the c:\ drive. After some investigation I found the SUSDB.mdf file was nearly 7GB in size.

I browsed to http://localhost:8530/wsusadmin/ and found that there were nerly 40000 updates on the system. I then went in and setup WSUS so that it only downloads the updates that we actually need. However I am still stuck with all these unwanted updates.

When I click on the updates tab, after a while I get an error saying something like "unable to contact database"

I have tried WSUSDEBUGTOOL.exe /tool:purgeunneededfiles. I get an error invalid tool.

I have also tried WSUSUTIL.exe deleteunneededrevisions. After some time I get a timeout error message.

I just want to delete all the stuff I done need. Any suggestions?

1/ Open the SBS console (manage server)

2/ Go to advanced management > Internet services (IIS) > Websites > WSUS Administration > right click WSUSAdmin and select the Browse command.

3/ To determine your version of WSUS look all the way at the bottom of the WSUS home page and you should see the build number (2.0.0.2620 if you are running WSUS2 SP1).

PS.

After you upgrade to 3.0 you will no longer be able to administer from a browser, you will need to use the MMC snap-in.

I can't install 3.0 as I get an error saying that I don't have enogh space , like I said.

The linked page only really addresses the PDF file and not the mdf file which is the one causing the problem for me.

I realize you say you are low on space. How large are your .LDF files??
Did you try what was suggested from the link(Restart Service MSSQL$WSUS)?
If you can get enough space to upgrade then the tools will help.
Here's a great article on how you can regain space by other means as well.
