Why do I not have more free disk space on Drive C: (OS) after running Disk Cleanup on Windows 2008 R2?

I noticed the C drive on my server was down to 10 GB of free space when earlier this week it was at 20 GB.  

I ran Disk Cleanup, checked every item (which totaled about 20 GB to delete).  I clicked Ok.

A window appears:  "The Disk Cleanup utility is cleaning up unnecessary files on your machine."

The window went away and I rebooted the Server.

After reboot, the amount of free space is still 1 GB, when it should be at least 30 GB.

Even my c:\Windows\Winsxs folder is 12 GB in size with the oldest file dating back to 7/13/2009.

Does it take time (after the Disk Cleanup) window disappears, to actually delete all the files discovered by Disk Cleanup?

Does Disk Cleanup really delete the files, or just moves them to the recycle bin?

Note:  The version of "cleanmgr.exe" and "cleanmgr.dll" running on the Server is 6.1.7600.16385 dated 7/13/2009.

Am I overlooking something?

Run Disk Cleanup again. Will it find anything? If yes, delete it.

Reduce the size of the WinSxS folder
Warning
Deleting files from the WinSxS folder or deleting the entire WinSxS folder might severely damage your system and make it impossible to restart or update your PC.
The WinSxS folder is located in the Windows folder on your PC (for example, C:\Windows\WinSxS). It stores the Windows Component Store files, which are used to support functions needed to customize and update Windows. You can use the Task Scheduler to reduce the size of this folder.

    Swipe in from the right edge of the screen, and then tap Search. (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
    Enter Control Panel in the search box, and then select Control Panel.
    Select System and Security, and then select Schedule tasks under Administrative Tools.
    Select the arrow next to Task Scheduler Library, select Microsoft, select Windows, and then select Servicing.
    Select StartComponentCleanup, and then select Run under Selected item.

With regard to:
Enter Control Panel in the search box, and then select Control Panel.
    Select System and Security, and then select Schedule tasks under Administrative Tools.
    Select the arrow next to Task Scheduler Library, select Microsoft, select Windows, and then select "Servicing".

I see "Task Scheduler Library", "Microsoft", "Windows", but I do not see "Servicing".

Looking at another solution:

Under Services:
1.  I set Windows Modules Installer from "manual" to "disabled"
2.  I cut and paste my c:\windows\logs\cbs\cbspersist*.log files to my D drive.  This freed up 12 GB on my C Drive
3.  I set Windows Modules Installer from "disabled" to "manual"
4.  I clicked "start" to start the Windows Modules Installer

But you have Windows Server 2008. It might not be available for you.

Nice. It's safe to move log files.
Have you run Windows Disk Cleanup again?

I just ran Windows Disk Cleanup.  There are no files to be removed.

What's odd, is that Windows Disk cleanup originally reported 20 GB of stuff to remove.  It then said "cleaning . . . ", then the window disappeared.  To me, that means it was finished with its task.  Yet, the free space on drive C was still 10 GB.  

After moving the CBS persist files, I now have 26 GB of free space on drive C.

Maybe there is something filling you disk. Monitor your disk hour-by-hour if the space is decreasing.

Maybe you were currently downloading Windows updates or so.
