The Creators Update may be bringing a boatload of features to Windows 10, but it still falls short of other useful tools despite months of development and testing with the Insider Team. Among others, the brightness slider is a no-show in the update, and many users aren’t happy with it. As if to compound the shortcomings in the latest version of Windows, the Creators Update also reduces screen brightness to 50% after each restart, as reported by one user.

A Windows user posted a complaint over at the Microsoft Community page about the brightness issues he’s encountered after upgrading to the Creators Update:

Since the Creators Update, my display brightness has been adjusted to 50% after each reboot. I have to manually select the appropriate brightness every time and Windows will forget this setting every time I restart. I am using a laptop. I think, it is not related to the new feature “Night Mode”.

Also, even after adjusting their screen brightness to 100%, some users get frustrated as Windows tends to forget their settings after reboot:

All the settings are as I want them to be. Advanced power plan with 100% brightness, disabled adaptive brightness. But after each reboot, Windows just forgets this settings. What I have noticed is that Windows 10 since the creators update is forgetting most of my power settings at restart. Brightness gets reset, adaptive brightness is turned back on each time. My Nvidia graphics card is up to date and I updated the driver for the Intel HD Graphics.

Microsoft has yet to issue a fix to the problem. Nonetheless, one potential solution could be updating the graphic drivers since they may no longer be compatible with the update.

I encountered the same problem with screen Brightness being reduced to about 50% after the update. I found that the automatic screen Brightness control was turned on. Once I turned that off the problem was resolved.

Yes, I have this problem even after I did a clean installation 🙁 and I’m using Asus X550JX.

Yes, I also have this problem. I didn’t see too much fuss about it, I thought I was alone. The problem seems to be caused by the Creators Update. In the previous versions of Windows I didn’t have this issue. It occurs both by updating via Windows Update or doing a clean install of OS. Tested. Hope for a fix!

I have this issue after windows 10 creators update. Although I go to control panel, power options, advanced options, display and disable brightness adjustment when the laptop is plugged in power, the option is enabled again each time I reboot and the brightness is reduced. I have tried everything I could think of including disabling all toshiba utilities (e.g. eco utility etc.)

I found this fix somewhere online, and it worked for me. It’s a simple fix, but if you don’t know how to use the registry(regedit), ask someone or backup before you try.

Go here in regedit, ComputerHKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4d36e968-e325-11ce-bfc1-08002be10318}000 then look for KMD_EnableBrightnessInterface2 in the right pane, double click it and change the 1 to a 0 and you must reboot after for it to work. That’s all, enjoy.
(If for some strange chance it didn’t work after restart, then go back and change the 0, back to a 1)
