Doesn't Detect Some Windows Uninstall Folders

On my windows xp sp2 computer with all windows updates, CCleaner 1.36.430 doesn't detect following uninstall folders for deleting them:

$NtUninstallwmp11$

$hf_mig$

$NtUninstallWMFDist11$

But option "hotfix uninstallers" in CCleaner is ACTIVATED.

And those directories waste 180MB of discspace - okay I can delete them by hand, but why do I have CCleaner?

Please fix, thanks :-)

CCleaner doesn't clean all the Hotfix Uninstallers, due to problems some people were having. I know the WMP11 was beta and MrG had it not to delete it, I will look into to it, and see if they need to be deleted or it.
