Hotfix Uninstaller option missing

It appears that, when running CCleaner on different versions of Windows, I am missing the option to remove Hotfix Uninstallers. It works on 32-bit XP, but not 32-bit Vista Home Premium. Can anyone explain this? Or at least provide a lit of when I can expect to have that option available?

There aren't any hotfix uninstallers in Vista.

Updates are installed in a completely different way. Explanation in this previous thread ...
