Windows 10 USB keyboard and USB mouse became totally dead
Out of the blue my mouse and usb keyboard stopped working completely (without any reboots). Feels like PC is dead, keyboard doesn't respond to num-lock or caps-lock, lights do not change at all. I tried to reboot: no way to fix, mouse and keyboard are listed in device manager as unknown devices that do not have drivers. Any clues what could be wrong, how to fix it?
Update:
While trying to do system restore to attempt to erpair the issue, my PC went into endless reboot loop where I cannot even start it now, not even safe mode. Fail code is: 0xc000021a

This happened to me too with the storage USB drivers when I prevented Windows from automatically updating.
You need to let widows itself update the specific USB device drivers that are no longer working because it's very likely that it will not let you use anything else, even official manufacturer drivers.
Use a PS/2 adapter or Keyboard and go to Device Manager and force-update the drivers via windows update system.
OvermindAppears the problem is Microsoft's fault and is related to KB4074588. Somehow they ended up pushing update that could remove USB drivers and would fail to install new ones.
I've had that problem a few times, today it happened once again and I tried to figure out what's going on. Randomly usb mouse and usb keyboard drivers would magically evaporate without doing any updates or restarts, in the middle of typing keyboard and mouse would suddenly "disappear". I tried to do system restore, this totally corrupted my system and I wasn't able to boot anymore (not even in safe mode). BSOD error code was 0xc000021a which is Bug Check 0xC000021A: STATUS_SYSTEM_PROCESS_TERMINATED. At this point google suggested to "Disable Driver Signature Enforcement" in advanced option, this helped to boot and restore evaporated drivers. However, they would again evaporate after a few hours of use. I tried to contact Microsoft, but got random copy-pasta recipe to check that connectors were ok or something like that.
Some googling and I found a large thread discussing this same issue on bleepingcomputer.com. In short, the solution is to uninstall KB4074588, suggested way by Microsoft, from admin cmd prompt:
For 32-bit versions of Windows:
