My Windows 7 came with Hotmail preloaded but I could not make it connect to the net! (I'm not savvy) My solution was - after three, hair pulling days - to uninstall it and go to the net and DL it. After executing it, it asked me for my usual password and then asked me if I wanted to make it my default e mail client, so now I'm fixed.
It may have not been the way others would have done it, but it worked.
Truth is I did that on a desperate lark and it accidentally worked.
