If you had read a previous comment on here of mine, it referred to your system getting 'bricked' or locked out with a hanging Blue Windows logo. I reminded others here that you must create a W10 MediaCreationTool DVD disk, reboot hitting any key and second time around boot without selecting any key still with the disk in your drive and selecting option F1 which is 'Debugging'.
The 'KB4056892' file is then rolled back without any need to reset the system and lose your apps in the process.
I used this method and everything was back to normal, and then I blocked the Windows update file.
