Instructions for installing normal Android instead of RemixOS on the tablet. In addition very easy to install the full Windows 10 for less money to get a tablet with two operating systems, not one. The video was a little longer to remove and install than to do all this. With the reinstallation of new Windows or Android tablet can handle almost anyone, so everything is automated. Only needed OTG cable https://goo.gl/2uh3cZ and USB HUB https://goo.gl/ybFwVC to connect a keyboard and a flash card.
