Windows 10: How Can I Change Display Brightness?

Starting with build 18912 and in 18917 (20H1), the slider for changing the brightness is missing from the action center. This has occurred on both the desktop and laptop PCs (Acer Aspire and Lenovo 1530 Flex). Using the manufacturers keys to change the brightness no longer work. All of the previous suggestions for this problem have been tried. The systems have the latest display drivers and all updates have been applied.


I suggest that some code changes in these two builds are the problem. I can switch to a different OS for either system (linux) and all display controls and SW work. It is only Windows 10 that has the problem.


Is there going to be any fixes soon or do we have to live with the brightness at 100%?
