Hi there and welcome
Do you mean windows live mail the program you installed within windows 7?
ok, you need to export them from windows live mail then import in the People App
To do this
Go to outlook.com and sign into your account
Then click on the 9 dots top left then People
Then click on Start Import
Then choose Windows Live Mail and it will import the contacts into the People list
You then see them on your comptuer
