Recently I bought iBall slide i701tablet which has "Windows 8.1 Single Language with Bing" OS. On specification for OS, it is mentioned that upgrade-able to Windows 10. I am checking regularly for Windows 10 update, but yet update is not available. So I wanted to know if anybody who has this table got Win 10 update officially (not through some ISO). On Amazon India, some people in review has mentioned that tablet has touch issues after Win 10 update due to lack of drivers. So is this the reason Win 10 update stopped by iBall?
