What advantages does windows 8 have?

Faster startup than Windows 7.

Expanded scope in system auto backup of user documents.

Added security.

But much more than that, getting into the modern mobile-era.

Windows 8 does introduce some specific advances where Windows 7 does fall short and I will list some of them here:

• Fast Boot – Windows 8 boots significantly faster than Windows 7, in fact on an SSD, I can have Windows 8 up and running in 5 to 7 seconds.
• Fully Touch Ready – This has been a miss on on prior versions of Windows going back to Windows XP Tablet PC edition. Windows 8 features a smart, fluid and fast interface that is significantly engineered for Touch called the Start Screen. There is just no disadvantage when using it with Touch. You can swipe, pan, zoom and do all the key actions expected on a Touch device. Microsoft has also created an environment that will encourage third party developers to create touch ready applications just for Windows 8. These applications will not run on Windows 7.
• Fully compatible with existing hardware and software. If it works with Vista or Windows 7, it is guaranteed to work with Windows 8.
• Tighter Internet integration – Windows 8 features a holistic integration with services that deliver information right to your screen without much need for you to find and discover it.
• The ability to sync information across multiple devices makes Windows 8 a truly Internet ready operating system.
