According to scattered reports collected by Windows Latest, a patch released by Microsoft on Tuesday is crashing some HP systems. KB4464330 reportedly conflicts with a specific HP keyboard driver, and IT staff on social media claim that the update is affecting many of their clients. Microsoft is still dealing with file deletion issues following the Windows 10 October 2018 Update, but KB4464330 "addresses an issue where an incorrect timing calculation may prematurely delete user profiles on devices subject to the "Delete user profiles older than a specified number of day" group policy." "We are having the same issue on HP prodesk 400 G3 Windows 10 machines today. It is definitely related to KB4462919 and/or the HP keyboard driver at the top of your screenshot. We do NOT push out any driver updates, and we are not using HP keyboards with these PCs," Reddit user R1PLEY explains.
