You should simply be able to do it by: logging in into your hotmail account and going to http://outlook.com while still logged in. After that, go into mail "More mail settings" (click on the upper-right gear) and choose "Create a Outlook alias" if you want to add e-mail aliases @outlook.com

But now that you already signed up for a new account it may not work straight away...

Yeah I don't have that option anywhere. I've seen other sites say that there should also be an option to upgrade but I don't see that either.

Maybe they're rolling it out in phases?

Oh well, it's not like I ever used hotmail to begin with
