Window 10 is the best OS by Microsoft.It provides lots of features which are not available in window 8 or 7.Its user interface is very good.I am not wrong if I say window 10 is smartest operating system ever.Its last update makes it more attractive.It provide all that features which we expected from an operating system.I am adicted to window 10 that I can not work on any other operating system.I just love it.
