I had to do 7! Win 10 Pro reinstalls after 1809 Update. HP Desktop could not start, could not boot, just a black screen. MS Customer support could not help. after numerous restarts I managed to get to repair mode. No other options available except to reinstall win 10 pro. done it once, 2 days it worked, new update comes in and no Boot again. Start all over again. 7! TIMES. MS! What tha Hell? Then I started making Sys Restore EVERY time I changed some settings in my PC. And...... Build in Skype. That is what caused all the problems. https://www.****/articles/uninstall-restore-windows-10-builtin-apps . I got rid of build in Skype, Now I do whatever I want, NO CRASHES!.
That wouldn't be the full story if Ido not mention that my ASUS T3 chi laptop did EXACTLY the same. I reinstall win 10 4 times there and as soon as I got rid of Skype all works.
Good luck!
