For Firefox users - there are plenty of plugins to allow you to use Windows Update I believe.
I have tried Firefox, but the amount of pages that get messed up by it annoy me. I use Maxthon - it uses the IE "engine" but has all the features of Firefox.
I use (like everyone else) firefox, because it has the ability to disable adds, does not take up to much bandwidth, and blah blah blah. oh yeah, and blah!
