Windows 10: MISSING BRIGHTNESS SLIDER!!!!

Hello,I am going to use the text of another person as it describes exactly what my problem is for my pc on windows 11.On march 3/3/2022 seallen wrote:"I'd really like help, because none of the solutions I've found online that supposedly fix the issue work for me. Before anyone answers, the option to alter the brightness IS NOT THERE. Not in the settings menu through the Start button, not through the network area on the taskbar, nowhere. There is nowhere on my computer currently to change the brightness, only to enable to stupid night light. Leeloofan: In my case the control buttons

Windows 10 - Screen brightness - Please bring the slider back

Hello Microsoft,

Please bring back the brightness slider and the volume sliders from the charms menu (slide from right). These were the features which were hugely useful and they are missing now. The stepped brightness setting is OK. But, we need the slider.

 

1903 - Broke On Battery Brightness Adjustment (missing sliders)

Got 1903 installed and now missing both of those sliders

I can still adjust brightness for Plugged In mode in the notifications menu and general brightness menu, but there is no way to set it for the Battery mode, when the notebook is unplugged.

Worked fine with 1809 and 17XX (with registry hack as it used to have brightness stuck all the way up).

Any way around it? I heard there is a reg hack that can be used.
Using older Mobile Intel 4 series express Chipset family driver from Microsoft corp WDDM 1.1.

Thanks for any input!

 

Missing Adjust Screen Brightness slider in Power Options

My HP laptop performed a Windows Update today. As a result, I've lost my "Adjust Screen Brightness" slider in Power Options. I can still find it in Settings - Display.

I have Win 10. I've found a YouTube video (specifically for Win 7) that suggests going to Device Manager - Monitors - Properties - Uninstall Device, but I've also read that doing so will merely result in the same driver being reinstalled.

What should I do to get the "Adjust Screen Brightness" slider back in Power Options?

Thanks so much for your help.
