Go to the device manager, find your keyboard in the list (which should still be reporting a “Code 39” error), and uninstall it. You should then restart your computer, and with any luck, your keyboard will work upon rebooting. If that doesn’t work, your keyboard may be physically damaged, or the drivers on your computer may actually be. Apr 20, 2017 Keyboard and mouse HID client drivers are implemented in the form of HID Mapper Drivers. A HID mapper driver is a kernel-mode WDM filter driver that provides a bidirectional interface for I/O requests between a non-HID Class driver and the HID class driver. The mapper driver maps the I/O requests and data protocols of one to the other. A HID device that presents itself to the OS as a keyboard or mouse shouldn't need any additional drivers. However, having said that, there have been some defects identified with HID devices. Hot plugging them may help on the current build. The next drop should resolve this issue.
So, yesterday my computer installed updates like it does every month. It usually has some problems booting afterwards but usually works itself out. But yesterday, after updating, my keyboard is not working. The number lock light is on and it is plugged in just fine. I went to the Device Manager to find that the keyboard (HID Keyboard Device) driver was missing and in the status it said Registry Code 19 or something along those lines. I found a fix on Google that involved deleting LowerFilters from the keyboard in the registry (regedit). This fixed the missing driver issue, but the keyboard still doesn't work. It says the keyboard is ready to use. I've tried two other keyboards. It works in the boot menus and BIOS. And yes, I have done System Restore, twice. Also, as previously stated, the number lock light is lit, but when I unplug the keyboard and plug it in again, it doesn't light up. I have also tried other USB ports and changing various keyboard settings. I have no idea what is causing this. Any help would be nice.
Also not sure if this is in the right category. Any help would be appreciated. Thanks.
