Fix: Windows 10 Night Light Not Working [4 Ways]

The night light is a feature of the Windows 10 operating system that limits blue light on the display at night to reduce eye strain and improve sleep quality. But sometimes the problem of Windows 10 Night Light does not work.

It's similar to Apple's Night Shift mode and Android's Night mode. However, if you turn on the nightlight on your device, the feature may not work properly, usually after you install an update, such as version 1903, version 1809, or versions preceding.

For example, the nightlight may not turn off automatically according to a schedule, even after restarting or shutting down the unit. On other computers, the blue light filter is grayed out and there is no way to turn it on. The Windows 10 night light is a nice feature that helps users to use their system longer. The color of the screen is warmer, which is especially useful when working in the dark or at night. That said, if for some reason you see that Night Light does not work, does not light up or is dimmed, here's how you can solve this problem. Like mobile phones and many other devices, computers running Windows 10 have a feature to filter blue light to make the screen more enjoyable for your eyes at night.

This function appropriately calls the night light. Sometimes it does not work as expected, however. The most common problem is that it does not turn on at the scheduled time. If you encounter this problem or other problem with the night light, this guide will help you solve it.

How to fix the problem "Windows 10 Night Light does not work"?

Here are some of the effective methods that will help you fix this error.

Method 1: Change the registry settings

The problem of Windows 10 with its Night Light feature comes mainly from two broken registry keys. Therefore, removing these keys forces the OS to recreate them from scratch. However, you must briefly dive into the registry editor to be able to do it.

Step 1: Press Windows-R to open the Run search bar. Now enter regedit in the Open field and click OK. This should prompt Windows 10 to launch the registry editor.

NOTE: Although you do not do anything drastic, it's always a good idea to back up your registry just to be safer before proceeding. To do this, click File in the Registry Editor window, and then click Export.

2nd step: Use the navigation pane to the left of the Registry Editor to navigate to the next folder (scroll down and down the field below to view the entire text string):

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionCloudStoreStoreCacheDefaultAccount

POINT: Simply copy and paste the path into the address bar at the top of the Registry Editor, then press Enter to access the folder more quickly.

Step 3: Expand the DefaultAccount registry folder, and then delete the subfolder titled $$ windows.data.bluelightreduction.bluelightreductionstate.

Then delete the subfolder $$ $$.data.bluelightreduction.settings located just below the previous one.NOTE: To delete, just right-click on a subfolder and choose Delete. Quit the Registry Editor and restart your PC. And voila! You should see Night Light fully functional in Action Center.

If that does not solve the problem, then let us update your video drivers.

Method 2: Update your drivers

Windows 10 offers considerable comfort due to the fact that it automatically performs most of the driver updates. However, in some cases, the operating system applies what it considers to be the "latest updates" of your graphics card or chipset if it is simply a generic display driver . To solve the problem, you must manually download and install the appropriate display drivers for your PC. Simply visit the NVIDIA, AMD or Intel download portals, then specify your graphics chipset to download the latest drivers.

After installing your drivers, reboot your system and you will probably not see dimmed Night Light anymore.

Method 3: Manually Reset the Nightlight Settings

Following these steps, reset the nightlight settings using the registry to solve the problem:

Warning: It is important to note that modifying the registry can cause serious problems if it is not done properly. You only need to proceed if you know what you are doing and if you have created a full backup of your system before continuing.

  1. Open Start.
  2. Type regedit and click on the top result to open the registry.
  3. Walk the following path:
    HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionCloudStoreStoreCacheDefaultAccount
  4. In the "default account" key (folder), right-click and delete the following two keys (folders):
    $$windows.data.bluelightreduction.bluelightreductionstate
     $$windows.data.bluelightreduction.settings
    Reset night settings on Windows 10
  5. Restart your computer.

Once the steps are complete, the pilot settings will be reset and the function should resume operation.

Method 4: Time settings can also be a factor

Windows sometimes has trouble syncing the time correctly. Here's how to check and fix the problem:

  1. Navigate to the Time and Date box on the taskbar and right click then click on it Adjust the date / time.
  2. Toggle Set the time automatically turn off and on, or change to Sure if it was off. This will allow Windows to synchronize with the time server.

If you are unable to synchronize with the time server, you will need to either change the server or set the time manually. Read on for instructions.

Changing the time server must be done from the Control Panel.
Here's how:

  1. Open the Windows search by clicking on it or with the Win + S shortcut and start typing "Control Panel", then click on its entry when it appears.
  2. Once in Control Panel, click Clock and Region.
  3. Now click on Date and time.
  4. In the window that appears, click the Internet Time tab.
  5. Now click Edit Settings.
  6. Click on Server in the drop-down menu and switch to another server, then click Update Now and wait. If it works, there will be a message of success. If that does not work, try another server. Click OK when you are done.
