Better on the inside: under the hood of Windows 8
Windows 8's most obvious—and most divisive—new feature is its user interface. However, it would be a mistake to think that the user interface is the only thing that's new in Windows 8: there's a lot that's changed behind the scenes, too.
Just as is the case with the user interface, many of the improvements made to the Windows 8 core are motivated by Microsoft's desire to transform Windows into an effective tablet operating system. Even those of us with no interest at all in tablets can stand to take advantage of these changes, however. For example, Windows 8 is more power efficient and uses less memory than Windows 7; while such work is critical to getting the software to run well on low-memory tablets with all-day battery life, it's equally advantageous for laptop users.
