Windows Server 2008 R2 SP1 cleanup of Winsxs folder

I have a Dell Windows Server 2008 R2 SP1 and the C: drive was apparently WAY too small as the WINSXS folder is running it right out of space. When I run WinDirStat it tells me the winsxs folder is taking up 70% of the C: drive, I am down to 800mb, ouch!!! So having all the windows updates done, I read about this winsxs issue and I am told to run C:Windowssystem32>dism /online /cleanup-image /spsuperseded in an elevated command prompt, which I do, and I get the attached error message every time, and no space is freed up. Other than having Dell install a bigger C: drive, how can I shrink this winsxs folder safely?
thx experts...

The only thing  you can safely do is follow the steps in this blog.

If you try to do anything outside of these instructions you risk the stability of your server.

If you don't get enough space back, your only option is to install a larger drive.

You might want to temporarily install the desktop experience to see if you get something different using the GUI instead of the command line.

OK, I read both posts and tried what they said and it all ran, but only free'd up 1.0gb of space.

Although these solutions did not free up much space, I did find an 8 gb file at the root of C called hiberfil.sys that I did not need so I turned off hibernation and the file went away and gave me some head room.
