Hi. I have the identical problem. Literally device arrive yesterday. Worked fine out of the box. As you run the system updates, touch screen stops working. Several Firmware and HID code 10 errors show in Device Manager.
Tried the Diagnostic Toolkit and all the standard recommended steps online / Microsoft forums. Touch screen does not work in UEFI.
Factory reset the device and everything started running again as out-of-box but as soon as you run system updates, touch screen stops functioning and Code 10 errors in Device Manager.
It is clearly not a hardware problem as device works perfectly when factory reset - something to do with updates.
This is also not a slim pen problem. Before anyone suggests, also tried to manually update the drivers/firmware and that does not work.
Poor customer experience and unbelievable that the problem stems from Microsoft own system updates. It's remarkable that 'Running system updates' is the proposed solution to the touch screen problem on the Microsoft forums when clearly it is the root cause.
Unless someone at Microsoft can walk me through a fix, will be returning the device.
