Today i tested installing the Win 8.1 in the normal way on my BT tablet and i have to say the "wimboot" method is just not worth it, after installing the S.O and drivers i have 20GB free instead of the 22gb with wimboot, and the tablet just feels faster, on top of that, it fixed the really bad wifi/BT performance, i was having issues with poor wifi performance and my BT mouse was slowing down if the wifi was transmiting data at the same time, that does not happen with a regular installed OS using the exact same drivers.
Im still having the very, very VERY bizarre problem wih the SD card reader, like a have a cheap generic 64gb sd that works perfectly on any pc BUT the tablet, if i plug it in the tablet, it works, BUT if i restart the Win 8.1 while the sdcard is inside, Windows will not be able to open the sd card anymore, i can shut it down OK, i can remove the sd card, restart and put it back in OK, but i cant restart it with the sd inside, and there is no way to fix it other than re-installing Windows.
What is just ridiculus for those tablets are the office and updates... Windows without updates = 20gb free, Windows after running Windows Update = 13GB...
