Windows used to have an email client that was just called Windows Mail. It wasn't Outlook and it was actually quite a nice little email client as far as MS software goes. They announced that it would be discontinued though for the sake of getting everyone into outlook. I started using thunderbird instead.
That's the one I'm talking about but it's not preinstalled anymore and they're taking it off the store at the end of next year so I decided to just leave asap.
