Can't disable Night light in Windows 10

Question

I can't disable Windows 10 Night Light, I have tried all solutions that I can found and nothing helps me. The only thing helps me - killing process dwm.exe, then night light disabled until display goes to suspend mode.

Video: Intel UHD Graphics 630

OS: Windows 10 21H1 19043.1706

Things I've tried:

• Different registry tweaks (for ex. https://allthings.how/windows-10-night-light-wont-turn-off-heres-a-fix/)
• Uninstalling video driver (installing then from Windows Update and from Intel site)
• sfc /scannow
• DISM /Online /Cleanup-Image /RestoreHealth

I don't want to reinstall OS, please give me any ideas to fix it.

Answer 1

I can't disable Windows 10 Night Light .... [tried] ... sfc /scannow, DISM /Online /Cleanup-Image /RestoreHealth

DISM / SFC did not work.

The (normally) best solution after DISM/SFC is a Windows 10 Repair Install from the Media Creation Link. Keep Everything and see if that works.

Windows 10/11 is running, so click on the Download button (not Upgrade Button) and select Run. This will launch the Repair. Proceed normally answering the prompts. The default Keep prompt is to Keep Everything

Answer 2

1. Try changing and saving Night light settings both logged in as a normal user and logged in as Administrator.
2. Check that Group Policy allows setting Night light.
3. As a work-around, change the time Night light is active to just 15 minutes. Do this as both user and Admin.

• Press Windows and type Night light in Search.
• Select the Nightlight CPL and turn it On.
• Select convenient times 15 minutes apart.
• You can also set the Strength slider to the minimum setting.
