[incorrectly flagging tweakui uninstall as a problem]

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.

[incorrectly flagging tweakui uninstall as a problem]

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.
