Windows 10: windows on laptop no longer recognizes keyboard

My Windows 10 installation on my laptop had an error and will no longer recognize the keyboard, nor will it accept an external keyboard. The keyboard works with the BIOS and a Win 10 install drive, but I can't seem to fix the problem. Is there a way to fix this or do I need to reinstall Windows?

If I need to reinstall Windows, is there a way to recover my product key without being able to access the Windows installation? If I have to do a "clean install" will it still be able to recognize the existing key?

Laptop Keyboard is no longer recognized in Windows 10

Your report suggests that something went wrong in Windows. I recommend that repeat Steps 1 to 5 above, then select "System Restore" to set Windows back to a point when the keyboard worked as it should.

 

Laptop Keyboard is no longer recognized in Windows 10

Overnight, by laptop keyboard stopped being recognized by Windows 10. I have a Dell Inspiron 7737, and the OS build is 14986.1001. No software or updates installed overnight, and the laptop was on all night, and not in sleep or hibernate mode. Any ideas?

 

Microsoft Mouse and Keyboard Center does not recognize Microsoft Surface Laptop keyboard

Problem:

1. I have a brand new Microsoft Surface Laptop, with Windows 10 Pro, which naturally comes with a brand new Microsoft keyboard hardwired to the laptop.
   
2. I installed the
   Microsoft Mouse and Keyboard Center to reassign some of the keyboard keys.
3. However, Microsoft's keyboard program does not detect Microsoft's own keyboard!

Failed solutions:

1. All the help pages say "update your drivers" or "unplug the USB device and plug it back in." However, this is a laptop keyboard, which is hardwired, not a USB keyboard. It is working fine, so there's no reason why the program should not detect it.
2. Yes, EVERYTHING is up to date, including ALL Windows Updates and ALL keyboard drivers.
3. Yes, I tried the troubleshooter.
4. Yes, I checked
   the list of "supported devices" that Microsoft lists here. But they are all mice, none of them are keyboards.
5. Screenshots of my steps are below -- Microsoft moderators, please don't dismiss me by saying "run the troubleshooter" or "update your drivers" or "turn it off and on again."

Questions:

1. Has anyone actually SEEN the Mouse and Keyboard Center recognize a Windows laptop keyboard? Not a USB external keyboard, the actual physical laptop keyboard?
2. Does the Mouse and Keyboard Center actually work with laptops? There's no documentation suggesting it shouldn't, especially with Microsoft's own hardware (like the Surface Laptop).
3. Where is there a list of what keyboards work with the "Mouse and *Keyboard* Center"?

Screenshots:

1. "No supported device detected"
   
   
   
   
   
2. "The best drivers are already installed"
   
   
   
   
   
   
   
   
   
3. "Keyboard troubleshooting has completed, no changes or updates were necessary"
