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

Hi David,

Don't hesitate to get back to us if you have other concerns.

I have tried to use the "Feedback Hub". Unfortunately I was unable to follow your instructions as the flow through the hub was almost entirely different. I did discover it was not possible to trace anything remotely like the BT keyboard problem introduced by Windows Update - so not able to add anything. The Hub experience was completely confusing (probably exactly what MS want) so I won't be wasting any more time with it.

Perhaps MS would respond using this forum - at least you can search and find the issue here...

For those following this thread who've reported sluggishness problems with the Microsoft Designer Bluetooth Mouse, I've created a problem report on the Feedback Hub for that, too.

Please follow the link to upvote this problem report, as well.

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.
