hidparse.sys BSOD bricks PCs on boot

Happy holidays! December’s update left a copy of hidparse.sys in the wrong directory, causing a version mismatch between System32 and System32\drivers. Windows signature validation failed on boot, producing a 0xc000021a Blue Screen of Death. The system was completely unbootable. Microsoft’s fix? Boot into the Windows Recovery Environment and manually copy the file with xcopy. No automated patch. No OOB update. Just a manual xcopy command that requires getting into WinRE on a system that won’t boot. Merry Christmas from Microsoft.
