Screensaver is not working after Windows update to 1903.

Was the same for me 

"I was running nVidia GeForce Experience and selected IN-GAME OVERLAY OFF and the screensaver and power saving started working again reliably."

turned that off and it works.

Using update 2004. No screen saver no matter what I do. After reading this forum, unplugged my Logitech Extreme 3D Pro and 2 minutes later my screen saver was working. Kind of annoying to have to unplug it, but I will live with plugging/unplugging it. Didn't need to reboot. Played FS2020 and when I was done, unplugged my joystick and waited 2 minutes and the sceensaver popped up. Works for me. Good input on this forum(not from MS but from users).

I have identified which windows updates are adversely affecting Windows 10 Screensavers.

Please check and remove these windows updates:  This issue is present between 1809 - 1903 and not just Windows Home/Pro, but also Enterprise LTSC 2019.

I am unsure if any version of windows post 1903 is working, and even if it is working, you cannot upgrade Windows 10 versions on Enterprise LTSC until a new image is created.

Note:  Enterprise users:  To fix this issue, go to services.msc and disable windows update service then uninstall these updates.  Also go to gpedit.msc and disable automatic windows updates.

Also Note:  I have reason to believe it is the security update in the screenshot that is affecting the screensaver settings specifically.

To Microsoft:  IF I am correct can I have a job, since I won't give people canned answers like your overpaid under educated software engineers who read from a script and only know how to use CTRL + C and CTRL + V?  I was laid off thanks to C19, and I do stuff like this in my spare time out of boredom.

I am on a HP All in One PC.  It has the Windows 10 1903 also.  I am having trouble

getting the Screensaver to work. I want to have it working. 

I tried the above and tried to update the display adapter driver. It told me it is up

to date.  Microsoft needs to fix this in the 1903 update they sent out.

Hi.  I had the same issue.  I did a clean install on my computer and needed to reinstall all the external programs after the full install with updates.  Before I wiped everything I put the screen saver programs on a USB drive.  Once I did that I copied my screen saver programs  back into the downloaded file.  I ran the programs again and most of them installed properly and run appropriately through the screen saver panel.  I have two separate laptops that talk to each other through syncing and network connections.  I suggest you copy the programs to the drive, download all the updates and then reinstall them again.   This bypasses the updates entirely and makes them usable again.  I no longer have any issues with them.
