I have Windows 7. Don’t like Windows Live and want to uninstall all of it. But nothing happens when I try.

When I try to email something that insists on using Outlook, Windows Live Mail pops up and says different stuff hasn't been polled and I can't use it.  I don't know what that means or how to "poll" or whatever it needs.  Very frustrating!!  I use AOL/ Internet Explorer and am happy with that email setup.  I'm not fond of Outlook, but sometimes that's all that's offered (trying to email from Microsoft Word, for instance.)   I would like to be rid of all the Windows Live components, but nothing happens when I try to uninstall.  All suggestions are welcome.
