windows live id, what is it, where can l find it.

l have a widows live id, hotmail, outlook etc email, but everything goes through my gmail account email,

for the life of me l cannot find what is my actual ............@live.com email address, l need this for a job application.

l have been searching all day, and everything reverts back to my yahoo and gmail email, its driving me nuts!

Can anyone put me in the right direction to find it?

Thanks for helping in advance....
