How do I Shrink the Size of the C:\windows\winsxs Folder?

I just took over a network with a Windows 2011 SBS Server

They Made the System Volume only 50gigs in Size and they are Running out of Space.

the Winsxs folder is taking up 38.5 gigs of that space

Is there a safe way to delete some of the files or can I expand the Drive to a newly installed drive?

Gotta love that.

We've solved this a couple of times in the past, one of two ways:
  • Virtualize the server, then manage the drives from there.
  • Move the directory and it's contents to another, larger partition then create a symbolic link there.

Have you tried Disk cleanup on c:\ and then selected system cleanup?  There is a KB for Windows 2008 for that, so I would think Windows 2011 sbs also has it.

In order to use diskcleanup you will have to install the feature, which will require a reboot, or do the installation hack.    It is just copying a couple files to the right places.  Here is one for 2008

Wow !!! That's Awsome......

Went here to get specs:

so to get this right,

I move the Winsxs folder first

then I right click on the new location Winsxs folder and pick as like source

Then browse the the Windows Folder and at the bottom Right click and Create a symbolic link...

When I tried to move the folder I get a: You require permission from TrustedInstaller to make changes  to this folder.

How do I get around that?....I searched for the Group in AD and could not find it...

You can seize ownership, and add the local admin and you should be able to do it then
Dustin SaundersDirector of OperationsCommented:
You should only need to grant permissions rather than take ownership.

Depending on space needs, you may also consider moving C:\Windows\Installer
