i bought s windows 10 and i,ve nothing but trouble with it, its quite a decent IOS when it does what its ask which recently has not been the case. My Windows 10 now refuses to function as its supposed to. When i turn on Nothing happens it won't let me scroll or slide the screen as it once did. The 4 symbols on the homepage are not responding to touch. Its a brilliant IOS that deserves a round of a applause .
