Re: I have reserved my copy of windows 10 ,

I am also reserve copy of W10 for my tablet (Encore Toshiba) but tablet did not automatically download update, only option for download is suggested way from WindowsCentral. But then after successful download and process of installation pop-up error 80070003. Does anyone has a clue what could be wrong?
Also, does anyone know what is necessary free space for upgrade?
