Hey I tried doing this but the button “Cleanup System Files” is not there.
This doesn’t seem to be a universal solution. I wasn’t prompted to run as admin, and the SP update files option wasn’t listed. However, when I explicitly ran disk cleanup as admin (Start > type “disk” > right-click and choose ‘Run as administrator’) the option above showed up, but reported that the SP backup files were taking up “0 bytes.”
My experience was on Win7 Professional 64-bit just after completing the SP1 install and the three additional reboots to get fully patched.
Goto start /accessories/system tools it is there as well
