I found it on my computer today. It says it's "...zero-configuration
networking, enables automatic discovery of computers, devices, and
services on IP networks."
Why isn't this on all the computes I have? Where did it come from?
iTunes has a number of component installers inside it. Bonjour is
one of them. There may also be a GearSoftware optical disc burning
package in there as well (to allow iTunes to burn a CD/DVD). The
components iTunes adds to Windows, sometimes screws up the optical
drive.
If you look inside the iTunes download file, you can see the separate
installers inside there. For a lot of this "look inside" work, I use
a copy of 7ZIP. It allows investigating installer packages, with
the exception of ones protected by InstallShield.

I have an archived iTunes package on disk here, and if I use 7ZIP
on it, I can see inside the package, the following components -
AppleMobileDeviceSupport.msi
AppleSoftwareUpdate.msi
Bonjour.msi
iTunes.msi <--- GearSoftware drivers are inside here
MobileMe.msi
QuickTime.msi
SetupAdmin.exe <--- probably what controls the installs
Inside Bonjour.cab (part of Bonjour.msi), I can see "mDNSResponder.exe".
On my old Mac, there used to be one of those running as well,
so that is likely a key component of Bonjour protocol.
HTH,
