A Microsoft account is an email address and password that you use to sign in to Windows. It's free and easy to set up, and you can do so with any email address you choose, or get a new email address. (For example, you can use an Outlook.com, Gmail, or Yahoo! address for your Microsoft account.)
When you sign in to your PC or device with a Microsoft account, you can get apps from the Windows Store, back up all your important data and files using free cloud storage, and keep all your favorite stuff—devices, photos, friends, games, settings, music, and so on—up to date and in sync.
If more than one person uses your PC, each person should have their own account. They can sign in and personalize the PC with their own background colors, favorite apps, account picture, a separate email inbox, and more. If you have kids, you can also set up a child's account with extra security monitoring measures—with or without email—so that your kids see only what you want them to see on the PC.
If you’ve used Microsoft services in the past—like Xbox, Hotmail, Outlook.com, SkyDrive, Messenger, Skype, or Windows Phone—you already have a Microsoft account (it's the email address you use to sign in). If you can't remember the email address you used with those services, that's okay—you can sign up for a new, free email address.

If you haven’t used Microsoft services in the past, you can use any email address you want to sign up for a new Microsoft account, including addresses from Outlook.com, Yahoo! or Gmail. To use your favorite email address:
