Those are vary similar boards, but I don't think there identical. On the bottom right of the Arduino there are 4 holes that line up with six others on the left side of the board. Note how there not parrellel with the bottom. Now compare that with the windows show it's got a line on the left bit it's not continued on the right side.
My guess is it's a different Arduino board or an x86 board that's trying to fit the same form factor which uses similar chips in similar places.
