Although Microsoft accounts make Windows easier to use, each account type has different requirements:

They also can not run many popular applications currently bundled with Windows, including the Mail, People, and Calendar apps. They also can not download apps from the Windows Store.
  • Microsoft Account: Mandatory access to many Microsoft services, which only include email addresses and passwords. Microsoft account holders can store files on the Internet with OneDrive, download applications from the Windows Store, and run applications that come with Windows, including the Mail and Calendar applications.

You can sign in with your Microsoft account in one of two ways, organized in a simple way:

  • Use an existing Microsoft account. If you already have an account with Hotmail, MSN, Xbox Live, Outlook. com, or Windows Messenger, you already have a Microsoft account and password. Enter the email address and password on the display, and then click on Sign In.
  • Sign up for a new Microsoft account. Click on Create one! , is shown in the figure and Microsoft takes you to a web page where you can create your own Microsoft account.
