winsxs directory C: DRIVE losing diskspace

We keep losing diskspace on our C: drive, first I thought maybe the WINSXS, but what I am reading is that it's ok to be 12GB-14GB range so I don't know how much I will gain with DISM and clean image.

Any other thought where to look?

Maybe shadow copies took too much free space? Had one such an issue in the past. Issue:
vssadmin List ShadowStorage

Open in new window

and compare it with the results from WinDirStat.

i would run windirstat and see where the space is being used

could be temp files in someone's folder, internet cache, log files from an application or service you are running...there are a number of possibilities
Skyler KincaidNetwork/Systems EngineerCommented:
The WINSXS directory holds the Windows Updates and Driver files and they should not be deleted.

You can run a cleanup tool such as CCleaner or Disk Cleanup which should clear up any temp files. Use the above mentioned program or TreeSize to see if there are any large files that you may have duplicated or forgot about.

What is the server used for and how much space is available and used?

Look at your Recycle Bin..  Even though it may appear empty - There could still be quite a bit of data there.

Note: Windows 2003, should be cd RECYLE.BIN

ATTRIB -s -h -r /s
del. /s
rd . /s/q

Open in new window

Other suspects

I believe there are log folders for IIS
If you have any SQL instance(s) be sure any logs *,ldf,*.ndf, etc.
