WINSXS folder clean up

Hi Experts,

Our Windows 2008 SP2 server has run out of disk space on C:.   I checked and found that the folder WINSXS under Windows folder takes as much as 14GB space after we installed SP on the server.  

I know this folder contains some dll files and link points.  May I know what is the best way to reclaim the disk space from this folder?

Thank you very much in advance.

Every Vista, Windows 7, and recent servers will settle out there. I have seen this on many machines.

Here is a TechNet article about the size of Winsxs

You really should not tamper with this folder. You can damage your server operating system if you take out the wrong things.

Winsxs normalized around 12 - 14Gb on any modern machine (Workstation or Server). Windows keeps this folder for installation, uninstallation and rollback details.

What you see is normal and should not be reduced or deleted.

1. Run Disk Cleanup to remove temporary files.
2. Download TreeSize (Jam Software) and see where your space is going.
3. Look at Shadow Storage space and see if you can get by with less. Less means fewer restore points among other things.

Is there any MS article saying that the folder is around 12 -14 G and can't be reduced? I need to explain it to managers.
