I wanted to try Windows 10 on my Winbook TW801, and it works well. However, I'm a little weary of the reporting home thing I've read about. I understand and agree with it, just I didn't think they'd be taking what I type. Again, I agree with their reasoning, just it isn't for me. I want to go back to 8.1, but as it came with 8.1 with Bing, and my backup of the recovery partition apparently didn't work, so I don't have that anymore. I have found that I can't really get Windows 8.1 with Bing without going to Microcenter (the manufacturer), which is in Atlanta and I'm in South Florida... I have a copy of 8.1 Pro on USB (with a legit serial of course), does anyone know if that is installable on a tablet that shipped with 8.1 with Bing?
