So I wanted to install this program called Optimum Tire but the setup kept failing. I asked the team lead for Formula Electric (as he is a CPE- computer progamming engineer or something along those lines).

Apparently my windows update has been deleted. As I do not know how to do this (only turn off automatic updates) I think it must have something to do with that rouge antivirus I had a while ago. The guy mentioned that those viruses can infect windows update and the antivirus that you use to remove the virus can then end up deleting infected windows update files instead of cleaning them. Anyway, that would explain the little messages about "such and such program updater has failed" that pop up when I start the computer. The computer still works fine otherwise.

I don't have my Vista disc with me but he recommended updating to windows 7.

If I update, won't that mean I have to reinstall all my programs? What about all my data ?(photos, documents, itunes library, etc.)

If I get the Vista disc can I repair it without affecting the other programs and such?
