I am having the same irritating issues, both at home with a Surface Book and at work with a Dell Precision, both use Microsoft Bluetooth Designer Keyboards and Mouses and W10, both work fine with their built-in keyboards and both miss the first few keystrokes from the BT keyboards every time focus changes, or after a short delay. Both BT radios have been set to NOT disconnect. All drivers are up-to-date on both machines and both worked properly up until the Fall Updates from W10.

It is difficult to see what can be to blame other than a defect introduced by MS so they need to fix as matter of urgency please.

Thanks.

I have problems with the Microsoft Designer mouse, too.  Frequently lagging, jerky movement - almost like moving through molasses.  The mouse also intermittently (maybe once a day) drops offline completely, requiring me to power-cycle the mouse to get it back online.

Per your instructions, I have uninstalled and reinstalled the keyboard drivers.  However, the problem persists after reinstalling the drivers.

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.

I have already tried to update the driver, but Windows says the latest driver is installed.  The MICROSOFT DESIGNER KEYBOARD AND MOUSE is new hardware.  The FCU broke it, and Microsoft needs to fix it!
