    Hello All,

    I bought a new tablet two days ago and instantly went and installed Windows 10 once I made sure it worked.

    After installing Windows 10 I've lost some functionality.

    • The Capacitive "Win" button and physical volume buttons no longer work (more on this below).
    • There is no auto-rotate option in the display settings, even though Device Manager can see the sensor (Kionix KXCJ9 Accelerometer SPB)
    • Camera is finicky. Each boot it fails to work unless I select "Update Driver" in device manager and choose the exact same driver from my local disk. Its listed as "Intel Imaging Signal Processor 2400".

    With regards to the physical buttons on the tablet, I went through device manager looking for anything relating to the GPIO Buttons. I found "GPIO Buttons Driver" and "Sideband GPIO Buttons Injection Device". Both are listed as working.

    Strangely, I also found a keyboard installed. Its listed as "HID Keyboard Device" and in the driver properties, it says its location is "on GPIO Buttons Driver". So I assume Windows has mapped the physical buttons to a keyboard driver, but I can't trigger any key inputs with the on-screen keyboard or text editor such as notepad.

    All of these functions worked in Windows 8.1 that came pre-installed. I cannot roll-back the system to 8.1 as the update to Win10 replaced the Win8 recovery partition with its own. I don't want to return the tablet to the manufacturer since they'll just re-image it with Windows 8 again, rather than fix the issues with Windows 10.

    Windows 10 32-bit
    Intel Atom Z3735G with associated Intel HD Bay-Trail graphics
    1GB DDR-3 1333MHz RAM
    32GB SSD

    Tablet Mode, Connect, Note, All Settings, Battery Saver, VPN, Bluetooth, Brightness, WiFi, Quiet Hours, Location and Flight Mode.
