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.

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\TweakUI] "DisplayName"="Tweak UI" "UninstallString"="C:\\WINNT\\rundll32.exe syssetup.dll,SetupInfObjectInstallAction DefaultUninstall 4 C:\\WINNT\\Inf\\Tweakui.Inf" This entry gets marked by ccleaners issues section as an uninstaller reference issue. It is a perfectly legitimate albeit unusual uninstaller reference.
