I've been trying to get my laptop (HP Envy 15T CTO) to install Cumulative Update KB3140745 with no luck. The machine gets stuck on 'restarting', and I have to power off. I have tried to jump directly to 3140768 by way of a standalone file downloaded from MS, but my machine rejects it with an error "this update is not applicable to your machine". I've tried SFC and DISM tools, neither show any corruption, so that's not the problem. Any help is appreciated. Thanks in advance!
