Once you have a Microsoft account, you can access all of Microsoft's online services. This includes several core services and tools, like OneDrive (previously called SkyDrive), Office Online, and Outlook.com.

• OneDrive and Office Online
  OneDrive is a cloud-based storage system you can use as your own personal online hard drive, with 7GB of free space. OneDrive is also integrated with Office Online, a free web-based version of popular Microsoft Office programs you can use to create basic Word documents, Excel workbooks, PowerPoint presentations, and more.
• Outlook.com, Calendar, and Messenger
  A free email service, Outlook.com makes it easy to send and receive email from anywhere. From there, you'll also be able to use Microsoft's other online services, including Calendar, which allows you to schedule appointments; and Messenger, which allows you to send instant messages to your contacts.
• Windows Essentials
  This is a suite of desktop applications you can download to your computer. Popular programs include the desktop version of OneDrive, which makes it easy to back up files from your computer; Family Safety, which lets you set parental controls for specific users; Movie Maker; and Photo Gallery. You don't necessarily need a Microsoft account to use these programs.

Why get a Microsoft account?

Cloud-based services like a Microsoft account allow you to access, edit, and share files from anywhere with an Internet connection. As these services become increasingly popular at home and the office, understanding how they work is becoming an essential part of computer and Internet literacy.

A Microsoft account is only one example of cloud-based services. Other popular services include Google accounts and Apple's iCloud. So how do you choose which service to use? In many ways, these services are so similar that you could choose one at random and still find it useful. All offer basic tools like file storage, email, and chat.

That said, if you already use Microsoft tools like Microsoft Office, Outlook, Hotmail, or Skype, you might find a Microsoft account easier to use than other services. Its document creation, sharing, and storage features were all designed to work well with existing Microsoft programs and tools. A Microsoft account even gives you access to a web-based version of Microsoft Office, called Office Online (previously known as Office Web Apps). Office Online is similar to the desktop versions of Word, PowerPoint, and Excel, which makes it easy to use—especially if you're already comfortable working with these applications.
