Windows 8 features a full-screen start menu with customizable tiles similar to Windows phones, making it more touch-friendly. It was designed for use on touch devices like tablets and includes built-in security and an advanced automated backup system. While Windows 7 requires third-party software for security and manual backups, Windows 8 provides these features out of the box. The operating systems have similar capabilities otherwise, but Windows 8 supports touch and includes a large app store.
