One of my least favorite things that Apple does to every Windows computer during an installation of iTunes is that it installs Bonjour. On almost every Windows machine I've installed iTunes on, Bonjour has caused an error of some sort.
As far as I can remember, I've removed Bonjour by deleting the folder it's in. Most of the time, this has not caused any major problems. However, I have a new installation of iTunes and I'm wondering if once again I should delete Bonjour.
Are there any issues caused by deleting Bonjour? Would I lose any functionality?

From Apple's knowledge base article about Bonjour on Windows (my emphasis):
If you don't use any features, then removing Bonjour won't cause you any trouble (except perhaps Apple Software Update might offer to install it again...)
Furthermore, this page has some instructions for more throughly uninstalling Bonjour.
