Ensure your system is running the latest version of Windows 11. To do this, press Windows key + I to open Settings, then navigate to Windows Update. Click Check for updates. If updates are available, install them and restart your PC. Updated systems often resolve bugs related to Night Light.
Open Settings by pressing Windows key + I. Navigate to System > Display. Ensure the Night Light toggle is turned on. Click on Night Light settings to customize schedule and intensity. Make sure the schedule is set correctly—either to turn on automatically during your preferred hours or manually.
Sometimes, simply toggling Night Light off and then back on can resolve minor glitches. Do this from the Display settings or Action Center. To access Action Center, click the network, sound, or battery icon on the taskbar, then click the Night Light icon to toggle it off and on.
A basic but effective step—restart your computer to clear temporary glitches that may prevent Night Light from activating properly.
Outdated or corrupted display drivers can interfere with Night Light. To update drivers, open Device Manager by pressing Windows key + X and selecting Device Manager. Expand Display adapters, right-click your graphics card, then choose Update driver. Select Search automatically for drivers and follow prompts. Restart your PC after updates.
Some third-party applications, especially display calibration or blue light filtering tools, can conflict with Windows Night Light. Disable or uninstall such software temporarily to see if Night Light starts functioning correctly.
If configurations are corrupted, resetting settings may help. In Settings > System > Display > Night Light, turn it off, then restart your PC. After restart, turn it on again and reconfigure as needed.
Windows includes troubleshooters to diagnose and fix common issues. Go to Settings > System > Troubleshoot > Other troubleshooters. Find Display or Windows Store Apps (if relevant) and run the troubleshooter. Follow on-screen instructions to fix detected problems.
If all else fails, resetting display settings to default can resolve underlying conflicts. In Settings > System > Display, scroll down and click Advanced display settings. Then, proceed to reset configurations or consider using System Restore to revert to a previous working state.
Common Mistakes
- Not updating Windows or display drivers before troubleshooting.

Troubleshooting
If Night Light still refuses to work after following the above steps, consider these additional troubleshooting tips:
- Check for Hardware Compatibility: Older graphics cards or integrated displays may have limited support for certain features. Visit your hardware manufacturer’s website for compatibility info.

To do this, type msconfig in the Start menu, select System Configuration, go to the Services tab, check Hide all Microsoft services, then disable remaining services. Restart and test Night Light.
- Reset Windows Settings: Use Windows’ built-in reset options or consider reinstalling Windows if the issue persists and is widespread.
