Windows Major Update KB4040724 - now desktop does not respond to the USB keyboard

RE: Update KB4040724

• Have you tried updating the keyboard drivers?

This is what I did today, Oct-3-2017...

I disconnected the keyboard…went through Steps 1-6 and the Keyboard still permits me to type 7-8 letters, them behaves in a strange manner…

Example # 1 - type a single "S"….and it inserts 10-12 "S's" without holding the key down.

Example # 2 - keyboard automatically establishes "NUM LOCK" or "CAPS Lock" and will not further respond.



I repeated steps 1-6... no response or control with the keyboard. This keyboard was in use with Win-10, from March-2017 until immediately (as in 1 minute) prior to installing the
Major Update KB4040724... then going through the required system re-boot...and immediately discovering the non-functioning same keyboard.



I repeated steps 1-6... plugged the keyboard in a different USB outlet on the desktop... desktop downloaded and installed the keyboard driver...same erratic behavior…and then received a Windows 10 error message "The USB device you just connected to
the computer malfunctioned and Windows does not recognize it".



NEXT STEP

- I disconnected the current keyboard…went through Steps 1-6.

- and then plugged a totally different mfg & model USB Keyboard into a different USB port.
I had used this different keyboard from Aug-2016 until March-2017 in Windows 10… without any issues.

Again…the desktop automatically downloads the required driver, and allows me to type 8-10 letters and/or digits….and freezes…unable to type letters or numbers.

New response...the keyboard is functional only on the "Windows icon" button…but does not allow me to enter letters or digits.

Q: Have you tried removing the recently installed update and check if the issue persists? Not yet ...but to encounter the identical problem on a totally different keyboard, in a different USB port, appears to be additional indications
that the problem resides with Update KB4040724 software, rather than the hardware drivers. That is just my opinion as a consumer and not as a Windows 10 expert.

Suggestions or comments appreciated. Thank you. / Ed

 

USB keyboard disconnects when holding any button down

Hi,

Thank you for contacting Microsoft Community.

I suggest you to follow the below methods and check if it helps.

Method 1: I suggest you to try the following steps and check if it helps:

• The USB connection may be loose. Try unplugging the keyboard, and then plugging it back in.
• Plug the keyboard into a different USB port.
• If your keyboard is plugged into a USB hub or USB switch box, try removing it and plugging the keyboard into the computer.
• Unplug other USB devices that are not in use.
• Try the keyboard on another computer to verify it is working correctly

Method 2: Also I suggest you to uninstall and reinstall the usb keyboard drivers as below and check if it helps.

• Press Windows+X and go to device manager.
• Then expand keyboards and right click on the driver.
• Then click on uninstall and restart the computer.
• It will be reinstalled automatically and check if it helps.

Booting to Command line and keyboard and mouse are not responding

Ok here are pictures of the commands and system restore message (apologies for my command line typos).







I have tried the keyboard in USB 2.0 and 3.0 ports, and in ports on the motherboard and case. I have not tried a second keyboard yet.
