    Open Start, Settings, Devices, Typing . On the Right Side, choose Advanced Keyboard Settings and see if you can remove redundant keyboards.

    Also try Start, Settings, Time and Language, Language. There are Keyboard settings there that might help. I have used this before but not entirely successfully.

  • @John If I right click one of these "HID Keyboard Device" and click "Uninstall Device", will something bad happen?

    Use care, but it did not hurt a Windows 10 machine I had that had 2 keyboards. Do not try to uninstall the main keyboard though.

Why not? ;-)

Keyboards (or other input devices) use multiple HID devices for various reasons. On keyboards, multiple devices are often used to make N-key rollover possible without relying on better HID support.

Keyboards are not the only type of input device that present themselves as keyboards. Mouses also often do, especially if capable of keyboard macros.

For example, consider the following:

device manager by connection

From top to bottom, it’s a “Das Keyboard” keyboard, a Logitech MX518 mouse and a Logitech G900 mouse. All of them present a keyboard.
