Windows is the best Windows OS by Microsoft. It has integrated the windows 7 with windows 8 to make 10. The start menu is has the metro styled tiles that shows the recent updates of mail or calenders it has all the shortcuts of apps that one can keep for easy access.
The aditional features has cortana and multiple desktop windows for multi tasking. It is really fast as compared to previous all windows versions. It takes hardly 10-15 secs to start and be in ready state to use. and equal time to shut down. The multi tasking windows is also nice and one can see all the tasks in one place. I really like the interface and appriciate the update.
