How to make a desktop software update with Windows Update?

Question

What I'm looking for is something like Ubuntu's PPAs: I want a desktop software from my company to update alongside with the Windows Update System, whenever I release a new version. Does Windows Update have an API for that, or something?

PS.: The software is made in Delphi.

Answer 1

Windows Update only delivers updates to Microsoft software, and drivers certified by the MS hardware labs. MS will not push out your updates. You'll have to do that yourself.
