Windows 10 missing first keystrokes from Microsoft Designer Bluetooth Keyboard after Fall Creators' Update

Hi Argel

I am using a Surface Book where the drivers are updated by Microsoft.

My keyboard and mouse worked perfectly before FCU. Since FCU they have been awful.

The keyboard misses keystrokes, repeats keystrokes and is generally slow to respond.

The mouse often lags many seconds behind the physical movement.

All the drivers are up to date, as checked via device manager. Windows Update is fully up to date.

FYI: I am a Microsoft MVP and ex-Employee of 13.5 years as an Escalation Engineer and this is something that Microsoft broke in the latest update and something they will need to fix ASAP.

Hi Evin,

If you're still experiencing the Bluetooth keyboard issue even after re-installing the keyboard's driver, there is a possibility that we may need to update the version of the Bluetooth driver. This the reason why we also want you and other community members to use another Bluetooth keyboard for us to isolate if the issue is with the specific Bluetooth keyboard or with every Bluetooth keyboard. If you do not have a spare or extra Bluetooth keyboard, we recommend updating the driver of your computer's Bluetooth to resolve the issue.

Kindly tell us if you can use your keyboard normally after updating the Bluetooth driver.

If that is the case, it is possible that there may be a problem with the keyboard's driver. This can be be the reason why you're encountering missing keystrokes when using the Bluetooth keyboard. We recommend that you uninstall and re-install the driver to resolve the issue. Kindly access this article to know how to uninstall and re-install the driver. Since the keyboard that you're using is a Plug and Play device (Devices that will automatically install its driver when connected to the computer), please follow the steps under Uninstall a device and Reinstall a Plug and Play device. Please be careful in uninstalling the driver of the keyboard. Make sure that you're uninstalling the driver of the Bluetooth keyboard and not the built-in keyboard.

After following the steps found in the link, kindly share with us the outcome.

I uninstalled the Designer Keyboard—twice—and it did not resolve the issue.  I followed the instructions from "Uninstall and Reinstall a Device" and was not prompted to remove the driver, so I attempted to use the instructions from "Remove a Driver Package from the Driver Store" but the driver (Microsoft Bluetooth LE Enumerator; C:\Windows\System32\Drivers\Microsoft.Bluetooth.Legacy.LEEnumerator.sys) was not found in the 'pnputil.exe -e ' output.  The only drivers from Microsoft were printer drivers.

Also, I notice the date of the Microsoft.Bluetooth.Legacy.LEEnumerator.sys driver is from 2006?  I think it's time for an updated driver.

I have tried a USB keyboard, and I have not seen the issue with it.

You're right. what I wrote before is not true. The problem continues to occur even with the wireless card turned off.
