Windows 8 login screen:
Windows 8 offers some great log-on options. You can choose to create a local account, but the OS becomes infinitely more useful when you use a Microsoft account. You’ll be able to synchronize to it your Windows 8 settings, including Internet Explorer history. This means that when you log in to any other Windows 8 machine with that account, your data will sync, including background settings, address book, other accounts like Facebook and Twitter, e-mail, and instant messaging.
