Welcome, I am Cory.
Do you mean it uses the program on your computer to open it?
I do apologize for the delay, I had to step away from my computer.
What I understand is that you want an account @hotmail.com and you already have @msn.com.
If you want that, you can just click http://bit.ly/29s4Gwa to get to the account creation screen and choose @hotmail.com when you sign up.
If you have any other questions, please do not hesitate to ask me.
