    Screen Flashes after 12/2020 Windows 10 Update


    Hello everyone.

    I searched Internet and could not find any information related to the problem.

    I have two Dell desktop PCs running Windows 10 Pro version 1909. I decided to upgrade to version 20H2. Everything was fine until I installed latest 12/2020 Windows updates. After rebooting and logging in I was presented with flashing screen and PCs were unusable. So I restored backup and went back to version 1909 on both PCs.

    But not such luck with Dell laptop with Windows 10 Home version 20H1. The same flashing screen happened after December 2020 updates. I restored good backup and disable Windows update. Well, today I turned laptop on and Windows update was running. After rebooting and logging in I got the same flashing screen and unusable laptop.

    What the f*\*/u*\*/c*\*/k is wrong with Microsoft?

    Here is video of the flashing screen :

    Any help appreciated.

    PS.

    Is it possible to disable Windows Update service on Windows 10 Home Edition so service does not restart by itself?

    :)
