Windows 10 by microsoft is not that much amezing. it is not that user friendly. only the interfacing part is good. it is a hybrid of w8 and windows 7. I think it is still in beta version because the 1st install and the 1st update both are not working properly. microsoft still has to do much with this.
It is still not available for mobile.i think it should be tested well before it is re launched for mobile phones. overall I will grade it average
