Got MS updates Windows KB4569745 and Security KB4570334. Turned screen on in morning, screen flashed white (several times/second), would not stop. Rebooted, OK. Same thing next morning. Uninstalled KB4569745, everything OK. The update reinstalled automatically, more flashing. Will try stopping automatic updates, uninstall KB4569745, see if this helps. Anyone else having this problem?

Bummer.

The flashing is likely caused by a driver, app, or device not being compatible with the Windows update.

Press Ctrl + Alt + Delete to open Task Manager. If you don’t see Task Manager after pressing Ctrl + Alt + Delete, press Ctrl + Shift + Esc to open Task Manager.

If Task Manager flickers along with everything else on the screen, a display driver is probably causing the problem. In this scenario, see https://support.microsoft.com/en-us/help/12374/windows-10-troubleshoot-screen-flickering

If Task Manager doesn’t flicker while the rest of the screen is flickering, an incompatible app is probably causing the problem. In this scenario, see https://support.microsoft.com/en-us/help/12374/windows-10-troubleshoot-screen-flickering

Task Manager not flashing. Instructions say to uninstall display driver. Said to start in Safe Mode, did, went to device manager, expanded Display Adapters, right-clicked the adapter, selected Properties. “Delete the driver software for this device” was not one of the options available.

Hello Curly,

When you right click on the graphics device, click uninstall then it should prompt you on whether or not you want to delete the driver for this device.

Are you using a dedicated graphics cards such as an Nvidia or AMD? or is it the integrated graphics card that came with the computer. If you can provide your make / model of your computer I can direct you to the latest version of the display driver and possibly see if there is a bug with the specified KB update.

Integrated card that came with computer. Dell, I3475-A509 (not sure of the first digit, may be capital I or shift-backslash symbol |). Will try your suggestion on the graphics device.
Thanks

Hello Curly,

Thanks for that information, Here is the driver download page for your device. Here is a direct link to the AMD Chipset and Graphics driver released June 2020.

After making sure you have installed all of the latest windows updates excluding KB4569745 you had removed manually, then I would then install the Chipset / Graphics driver from the dell support page. Thereafter I would check Windows updates one last time to to make sure everything is up to date.

Let us know how it goes.

Installed the latest driver, reinstalled KB4569745, checked Windows updates, everything OK.
Thanks for the help!
