I noticed today that the "Disk Cleanup" utility isn't available by default on Windows Server 2008 R2.
              However, to add it, you need to go to:
              
                - Control Panel
 
                - Programs and Features
 
                - Turn On/Off Windows Features
 
                - Under "Features" section, hit on "Add Features"
 
                - Then select "Desktop Experience". It will ask for a dependent feature to install also, accept and continue.
 
                - A computer restart is needed
 
                - Now, you can use the "Disk Cleanup" utility to free some space
 
              
              
              Hope this helps,
              Regards
