Microsoft Window 8.1 is the best Microsoft Operating System. Now I am currently using this OS because this is very very good then other.
The most important point is its work fast then other all OS and all type of application is support easily. Microsoft released window 8.1 with Update 1 so this is awesome and the OS 8.1 graphic design very cool then other all OS. its easy to understand and easy to handle but just one bed think when we want to shutdown our system process is lengthy but I like new different features
