These two are from a brand new feature, they both read REGISTRY entries which keep track of recently opened documents and launched files.
It turns out that the %SPECIALSYS_APPS% one is basically useless (at least for now), which is why it's disabled by default, since windows only seems to track recently launched INSTALLERS.. not something you'd often want to search for again.
But the %SPECIALSYS_DOCS% is useful list of recently opened documents.
You can disable these if you don't want them -- they simply make it faster to find recently opened files.

hey that's a good idea! ill see if i can't add this as a feature somewhere.
