Server running out of space winsxs

I have a virtual server which is partitioned so that the C drive has 50GB and the D drive has 250gb
However the space keeps running out on the C partition, due to the increase in files in winsxs. I am no down to 2GB spare which will be take up by new winsxs files in the next couple of months at the current rate.
I have added service pack 1 (I am on windows web server 2008) which then allowed me to run a job (SpSupeseded) to remove files.
If I now add service pack 2 http://www.microsoft.com/en-us/download/details.aspx?id=17669 will this allow me to free up more space or will it just take up space. How else can I clean up space on the server. even though it is a virtual server I cannot extend the 50GB space

You should be able to use the superseded again.

The command is
Dism.exe /online /Cleanup-Image /SPSuperseded

Open in new window

OK I will try.
I will leave this open until after trying the update to let you know if it is successful.
In the meantime I have reduced the swap file on the server which has created a lot of space, but will no doubt affect performance and does not fix the issue of the ever growing winsxs folder

Move your page file to the D drive, rather than reducing, as VM it'll still function the same. Assuming your vhds are on the same LUN or vdisk.

Moving the pagefile will not affect your performance if they are on the same LUN (i.e. partitioned space).  But, if they are on separate LUN's, You will get a small boost in performance.  

But, if you aren't using the pagefile, you shouldn't take a hit from it.  I'd check your pagefile usage to see how it is.  The recommendations for the current versions of windows are generally ridiculously high..  As long as I am able to keep my pagefile usage down, I stick with the 4gb pagefile, even on large servers.

And of course, make sure you are removing unnecessary profiles, deleting/compressing unnecessary logs (like IIS logs -- they are generally not really needed, and will compress *dramatically*.  Clear out your \windows\temp directory.

This is a known issue with the winsxs folder growth.
You can run the cleanup tools (DISM) suggest by Microsoft but that typically doesn't reclaim a heck of a lot of space. It just removes the installation files for the service packs.

Here is some reading on why the WINSXS folders grows so much.
