WSUS Server Cleanup

I need help advice with disk space on WSUS server. There is a single volume and I am running out of disk space. I've already used WSUS Server Cleanup Wizard and now running out of options. Can I possibly compress WSUS folder? Any other options?

is this a physical or virtual machine?
do you have the ability to add any space by either physical disks or virtual?
i don't think file system compression will yield much since they are binary files and usually don't compress much
how big is the volume and how big is the wsus folder?
exhuserAuthor Commented:
It is a physical machine.

Can I possibly go to All Updates and manually decline some really old ones?
exhuserAuthor Commented:
The volume is 150GM and WSUS is more than 100GB

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

wow that seems a bit large
i would go through the updates and see which ones you don't need or are superseded
if you click on 'all updates' then on the right, right click on any column header and you can add supersedance and sort that
the icon in that column looks like a little org chart.  if the blue is on top, it means it supersedes another update and you should keep that.  if the little blue square is in the middle or bottom it means it is superseded and you can decline it

you can also add the 'needed count' column and sort on that.  if there is 0 then there are updates not needed
i would also check the categories to make sure you don't have products selected that you don't have like older windows or office versions.  you sometimes need to do a little manual work before the cleanup wizard can do much

Where do I check/configure the categories?
Seth SimmonsSr. Systems AdministratorCommented:
click options on the left then products and classifications on the right
