No Night Light

Hi allisonb1

Try these steps

Option 1. Reset Night Light-related Settings on Windows 10 Fall Creators Update

If you find the night light in the Action Center or the Settings is greyed out after the Windows 10 Fall Creators Update, you can fix it with the steps below:

Step 1. Use Windows shortcut keys Win + i to open Settings.

Step 2. Go to the Privacy menu.

Step 3. On the left side, choose the Location tab.

Step 4. Click the Change button under the Location for this device.

Step 5. Toggle the switch under the Location for this device to ON.

Step 6. Toggle the switch under the Location service to ON.

Step 7. Restart the computer.

Now check the Action Center or the Settings on your Windows 10 Fall Creators Update to see if the night light feature is available.

Option 2 . Modify Registry to Fix Night Light Not Working on Windows 10 Fall Creators Update

If the methods above didn't work, you may need to modify the registry to fix the greyed-out night light button or the night light not working issue. Note: Windows Registry is a vital database on Windows OS computer. Any misoperation will cause server system
problems, such as 100% disk usage issue, blue screen issue, endless reboot, etc. So it's important to backup registry before the changes.

Now let's kill the night light not working and release the pain:

Step 1. Use Windows shortcut keys Win + R to launch Run.

Step 2. Type into regedit.

Step 3. Hit the Enter key.

Step 4. Copy and paste the path into the address bar of the Registry Editor: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount

Step 5. Press the Enter key.

Step 6. Right-click the key $$windows.data.bluelightreduction.bluelightreductionstate under the DefaultAccount and select the Delete to remove it.

Step 7. Right-click the key $$windows.data.bluelightreduction.settings and select the Delete.

Step 8. Restart the computer.

Then you can go to the Action Center or the Windows Settings. The night light not working issue has been resolved now and the night light button is available.

Screen colour temperature changes at login (as if Night Light is enabled, though it isn't)

So I've been trying to troubleshoot this problem on and off for a couple of months.

Photos:

Warm (Night Light effect)





Normal (after color management/calibration tool)





I have two Windows profiles on my computer. When I log into my main profile (even before it reaches the desktop), all my monitors get an orange hue as if Night Light has enabled. This persists through the login.

Occasionally while using my main profile, the screen colour temperature will flicker back to normal briefly, but it always seems to return to the Night Light effect.

The ways I have found to get the colours to return to normal (temporarily):

• Run the "Calibrate display color" tool and click through the steps (without changing any settings).
  
• Run the "Calibrate display color" tool and say no to the popup asking if I want to create a Windows color profile given my displays support wide color gamut.
  
• Run the "Color managment" tool and set the default color profile to any of the color profiles available for each monitor.
  

However, as soon as I log out or restart and log into my main profile, the warm filter re-applies itself. When I select my secondary profile to log in this Night Light effect does not occur, and even turns off if it was previously active.

I've tried turning on/off Night Light - the screen does get slightly warmer with it on, so it doesn't appear to be Night Light malfunctioning.

I've tried turning off all startup apps (I use Rainmeter, DisplayFusion and Twinkle Tray) - no difference.

I've tried disabling NVidia GeForce Experience - temporarily reverts to normal then after an arbitrary amount of time the Night Light effect returns.

I've tried disabling NVidia drivers, uninstalling and reinstalling them as well - same result as above.

I've tried following the specific steps in this post about the same issue: Redirecting

I've tried changing settings on the monitors themselves, but it doesn't affect the Night Light effect.

Monitors:

3x ViewSonic VX2705-2KP

Windows 10 build 19044

NVidia Graphics Driver version 526.98

PhysX System Software version 9.21.0713
