I am sure you still can't uninstall Internet Explorer. In 1995, you often needed to install Internet Explorer (4 or 5) in order to play certain games because it required certain features/libraries.
It was kinda odd that they bundled the Internet Explorer with, IIRC, King’s Quest VII. We had no internet connection and it was baffling to have it to be installed.

For compatibility reasons (or just spaghetti code), I guess you still need to have an IE available if a program does a simple check that you have the libraries (and not, oh my god, Netscape!)

I have Bonjour running right now as my iPod Touch is charging and it basically acts as a network driver from iOS <-> Windows. The name of Bonjour is btw. shown as "mDNSResponder", who knows for what little bit of work this is needed.

Maybe a leftover of a cross-platform launcher or something?

Sincerely,
