How to fix windows update error 80072EFD in Vista SP1

I was working on a computer with a bunch of viruses / malware on it (it had no A/V previously) and a bunch of things were messed up. No firewall, no windows updates, network stack wouldn’t start, etc. etc.

One of the things on my list was to get windows updates to work again, and apparently one of the viruses enabled a proxy server for windows update and it changed it to some weird port (obviously a tactic of the virus to disable / re-route windows update traffic).

This is how you reset the windows update connection settings back to the default (no proxy server).
