Honey, welcome to the forum! I had problems with Thunderbird, Windows Live has a full, free email suite. There's also extra's, such as a picture gallery & movie maker, messenger, family safety, toolbar & writer. That's as much as you can expect from a free service.
It should be available to you through Microsoft Update, an upgrade from Windows Update. On the Windows Update page, you see a link to get free software from Microsoft, this is where you'll find it. You'll have to agree to install Microsoft Update to get to it, then your update scanner will shortly show you the updates.
Make sure that all of your other updates are installed first, I don't know if MS update will find everything that Windows Update will.
Should you need further assistance, always feel free to post. This forum is a really good place to learn Windows 7, and there's plenty of friendly, qualified help here.
Best of Luck,
Cat
