Windows 10: Duplicate Keyboard listings in Device Manager cause failure to connect

My Bluetooth Apple Magic keyboard does not work at startup. Each time, I have to connect it by USB cable, then remove it even though it is marked as "paired" and re-connect it by Bluetooth. There are two listings for an "HID Keyboard Device" in the Device Manager, but I have only the one keyboard on this computer, which is an iMac running Windows 10 under BootCamp. There are also two listings for a keyboard in the Bluetooth devices section. And finally, there is also a separate listing for "Apple Keyboard" under Human Interface Devices.

Device Manager Un-Hiding Hidden Devices

When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

Device can be disconnected when

• Device unplugged (e.g. removing a USB device)
• Turning a device OFF
• Disabling the device in BIOS (then windows won't detect it) or
• Device failure

So

• Check BIOS as suggested
• Check board connections
• Can b/t be turned off by a switch? or keyboard combination?

Also possible the b/t h/w failed

 

More than one listing in Device Manager

In addition to the resolution, we suggest that you uninstall both keyboard drivers from the
Device Manager of your PC, and then restart your device to automatically reinstall the appropriate keyboard driver on your computer. To do this, you may follow the steps below:

• Click Start, type Device Manager, and then press
  Enter.
• Expand the Keyboard section, right-click on the device driver, and then select
  Uninstall.
• Follow the on-screen instructions to complete the process.
• Uninstall both drivers.
• Once you’re done, restart your device and check if the issue persists.
