Microsoft windows 7 vs. windows 8
Microsoft windows will soon come to the market as a commercial Operating system. However most people have installed the preview copies given by Microsoft before releasing the actual product and they are going to compare windows 7 and windows 8. But the original commercial version will be very different from the preview copies.
It will be faster than windows 7 when starting up and also when shutting down and hibernating. Since windows 8 is developed to run in any platform especially on touch screen mobile devices such as phones and tabs it saves power over 35% than windows 7. Also it comes with great set of apps which will allow you to do almost anything from photo editing to advance hardware management without any other expensive 3rd party applications.
