TechThisOut!

You can get a Windows Live Mail! account for free. It’s a small exploit that was discovered by someone and it really works. Alright, let’s start!

1) Open up Internet Explorer. MSN likes Internet Explorer, and hates Firefox.
2) For this to work, you must be signed out of MSN. Go to the MSN Homepage, and double check you are signed out.
3) Copy this URL to Internet Explorer: Right Click On Here -> Copy
4) You should be redirected to another URL (Another URL to login). Sign in.
5) You should see the regular hotmail once signed in.
6) Once you see the regular hotmail, do Step #3 again. Copy the same URL above.
7) Click ‘Join Mail Beta’ on the bottom (Scroll down!) and voila!

Edit
Unfotunatly this workaround no longer works.
