Dear Sir. I am having the same issue. I am pretty good with computer stuff, but this a little beyond my comfort zone. If Root was made available, Titanium backup would be the answer, and we would all live in harmony. Hopefully, somebody will come up with an easier root method. I saw the USB partition options, but most are in chinese, need translation, and I am just not comfortable with that. I am with you on the android usage. I like having the windows 10 tablet, but I do not really neeeeeeeeeeeeed it. I would be more likely to ditch the windows partition, but it seems to me for now the android portion in a little sluggish. Hmmmmmm maybe its becasue we only have 4 GB or Rom to work with… lol. I hope we find our answers, if I do I will share with you here.
