Normally when you want to access the Disk Cleanup tool, you usually have to either find it through the start menu, or open up the drive properties window. Instead of going through all that, we can use a simple registry hack to add a menu item to the drive right-click menu.
Manual Registry Hack
Open up regedit through the start menu search or run box, and then browse down to the following key:
Create a new key called “diskcleanup” and set the default value to “Disk Cleanup”. Then create another key underneath it called “command” and set the value to the following:
cleanmgr.exe /d %1

Downloadable Registry Hack
Simply download, extract, and double-click on DiskCleanupDriveMenu.reg to enter the information into the registry. You can use the included RemoveDiskCleanupDriveMenu.reg file to reverse the changes

And then disk cleanup will begin:
