I recently bought a 'bundle' at a car boot sale and among the goodies I actually wanted was a Windows tablet. Cheap thing I think. The seller told me it needed an operating system. It powers up, displaying the Energystar logo etc., but then nothing. It's still 'on', you can see the backlight is on, and there is a a small dot that follows your finger around the screen. Assuming the seller was right, my question is: is there a tablet-specific version of Win 10? I have noticed some tablet-friendly features on my win 10 laptop which makes me think maybe any (compatible) version might work but it would be nice to have some guidance. Then there's installing it. The tablet only has a microSD port. Is there a clever way of installing from a microSD card? TIA.
