How to short the long URL?

Here, I want to introduce this 3 URL shortener provider,

1. Google URL shortener
2. TinyURL
3. Bitly

Each of them also can help you to short the URL you want.

Before the URL is:

https://login.live.com/login.srf?wa=wsignin1.0&rpsnv=11&ct=1365487341&rver=6.1.6206.0&wp=MBI&wreply=http:%2F%2Fmail.live.com%2Fdefault.aspx&lc=1033&id=64855&mkt=en-us&cbcxt=mai&snsc=1

After use the Google URL shortener:

http://goo.gl/Gyu6ib

After use the TinyURL:
http://tinyurl.com/l9oyfdy

After use the Bitly:

bit.ly/1ijeDGP

All of them are very easy to use, so no tutorial :)
