This entry gets marked by ccleaners issues section as an uninstaller reference issue.
It is a perfectly legitimate albeit unusual uninstaller reference.
Full Version: incorrectly flagging tweakui uninstall as a problem
Make sure the "C:\Winnt\Inf\Tweakui.inf" file listed in your post exists on the hard drive, other than that I don't know why CC would flag an uninstaller other than if it had a missing file. "Perhaps re-installing Tweak UI will fix the issue."
Wow!! My mistake. This is an MS bug. It turns out that the rundll32.exe was in winnt/system32 not winnt.
Sorry for the incorrect report.
