I am just googling for the very same thing! In fact, this is how I came across this topic.
Can we expect that in the (near? ) future this will be added to the CCleaner? Since there are, at least, two of us?
To be hones, I am also a bit disappointed, that, even thou there is an option in "Registy section" to check MUI Cache, some values are not wiped. Even thou phe path is incorrect - there are values pointing to my usb flashdrive which is no longer mounted.
