Are you sure this is a fresh install? You seem to have an awful lot of programs installed.

In any case, the most likely culprits are the pagefile and hibernation file. You can adjust the former manually and disable the latter completely if you never hibernate your system. (These two files probably account for the "unscannable" area in your screenshot as well.)

Also, if you installed Service Pack 1 or otherwise downloaded/installed a lot of Windows Updates, these can be safely deleted from C:\Windows\SoftwareDistribution\Download. For SP1 there's a special command tool to remove backup files created during the installation of SP1.

^ You can also use the Disk Cleanup tool to remove the service pack backup files.

i followed the procedure in disk clean up to delete service pack 1 files but its already showing 0 bytes without me doing anything:shock :....
