I think Disk Cleanup in Windows 10 is buggy, has been since release. I've also reported this to MS, even had 2 MS techs on my computer to show them. It reports files to delete, that are no longer on...

I got 5 of these DrUpdate.dll in mine. Anyone know what they are by any chance. ??
Nevermind I just checked its a Driver servicing tool by MS :)
