I have successfully downloaded Windows Live Mail (eventually!) I can't find how to access my contacts list that I had in Windows 7. Any ideas on how to do this, please?

Sorry, I didn't make myself clear. I have bought a new laptop with windows  10 installed. I have installed Live Mail, but cannot find where my contacts list should be. My old laptop runs on windows 7 and has my contact list in Live Mail. How do I access this in windows 10, please?
