PLEASE stop advising that a rollback to OS 1803 or a fresh install of the OS fixes problems caused by update 1809. They don't!!! And the issues caused are FAR more extensive than the 'few' admitted to by MS (why would they admit more?). I have two near inoperable laptops to prove that point!
Further, today's update KB446330 has NOTHING to do with repairing 1809, that is obvious in reading on it! Stop making uninformed guesses on the issue gentlemen!
