I use IE at work. It has a nasty habit of forwarding searchs to MSN search, which also pops up ads on my screen.

What I want: if it's going to do autosearch, at least use Google.

The solution: customize IE with some registry hacks provided by our friends at Google: http://www.google.com/google.reg

Just save the reg file locally. Double click to import into the registry. You're set.
