While deleting some files on windows XP, I get this message
"Deleting this File Will Make some Programs not Work"
I want to know weather I can produce a particular message, like above, when a file gets deleted.

(May be I need to monitor certain files using hook, and when the hook notifies me of their deletion, I show a messagebox like above. But I want to know how "windows" do it).

I'm assuming there is an explicit place in the registry for this, or windows scans part of the registry for file links and reports message when found.
