However, this feature may interfere with manual brightness adjustments. To disable adaptive brightness, go to "Settings" by pressing Windows key + I, then navigate to "System" > "Display" > "Change brightness settings." Under the "Brightness and color" section, disable the "Change brightness automatically when lighting changes" toggle.
4. Adjust brightness from display settings: If the above steps do not work, you can try adjusting the brightness directly from the display settings.

Ensure that you click on "Apply" to save the changes.
5. Check for software conflicts: Certain third-party software or display management applications can interfere with brightness controls. Temporarily disable or uninstall any such software to check if it resolves the issue. You can also perform a clean boot to start Windows with only the essential services and programs running, eliminating any potential conflicts.
6. Run the Windows Troubleshooter: Windows 10 provides a built-in troubleshooter that can automatically detect and fix common system problems. Open the "Settings" menu, navigate to "Update & Security," and click on "Troubleshoot" in the left sidebar. Select the "Additional troubleshooters" option and run the "Display Quality" troubleshooter. Follow the on-screen instructions to complete the troubleshooting process.
7. Restart the Windows Explorer process: In some cases, the Windows Explorer process responsible for the desktop interface can be the cause of the issue. Open the Task Manager by pressing Ctrl + Shift + Esc, locate the "Windows Explorer" process in the "Processes" tab, right-click on it, and select "Restart." This will restart the Explorer process and may resolve any associated issues.
8. Reset or reinstall Windows: If none of the above steps work, you may consider resetting or reinstalling Windows as a last resort. This will restore Windows to its default settings and fix any software-related problems. However, make sure to back up your important data before proceeding with this option.
Remember to test the brightness adjustment after each step to determine if the issue has been resolved. Consulting official Windows documentation and forums can also provide additional insights and solutions to specific problems related to brightness settings in Windows 10.
