Gee, there's an idea. Ask for passwords before installing files! Windows can't do this! OMFGPWNED!!!

Oh wait... Run as a restricted User Account! Want to install software? Right-click -> Run As... What do you know!? You have to enter a password!

As for giving it up, if there's plenty of Windows vs. *nix discussions across this board, why are you here?
Because there's far more you can talk about in regards to security than just "Which OS is more secure"? That's why.
