Email access?

On both laptop and Desk top Pc when trying to get to my emails I get a message said to be from windows live ‘ We need to add some security information for your account if you ever forget your password we need a way to reach you. It then asks for alternate email address, a telephone number, the name of the computer. It then give ‘3pigs’ as a security question with the option to change.
Is this for real or a scam for access?
I can get to emails on laptop by clicking the white cross in red box then clicking ‘close current window ‘ then accessing the email address and it goes straight to my emails but cannot do this on the Desk top clicking the white cross in red box closes the net connection and PC is where I print out some emails have to access them on Laptop copy to word and transfer to PC via dropbox. I tried clicking send on the message and not filling anything in and it went but accessing emails again back came the message.
