While working on the computer for long hours, continuous exposure to blue light can cause eye strain and disrupt sleep patterns. Microsoft introduced the Night Light function with Windows 10 Creators update in 2017. The feature that switches the screen to warmer tones is excellent. However, it sometimes stops working due to several reasons.
If you also encounter issues with the night light or cannot turn it on on Windows 10 or 11, We’re here to help.
Now that we know the problem and what can cause it, let us explain how to fix the issue of the Night Light not working on Windows 11,10.
Before we learn the technical ways, let’s check whether the Night Light feature is turned on. If not, follow these steps to get Night Light enabled:
As reported by some users, wrong date and time settings can also be the reason for Windows 10,11 Night Light greyed-out issues. Therefore, to fix it, try checking the data and time.
Sometimes, when the strength of the night light is weak, you might face issues with it not working with Windows 10. To fix it, make the following changes to the Settings menu.
The location service on the PC should be enabled to get the night light feature working on Windows 11. This helps us know the time of day and evening. Therefore, if the Location service is disabled, you might face Windows Night Light grayed out. To enable the Location services, follow these steps:
A corrupt or problematic graphics card driver can sometimes set off Night Light. We suggest updating the graphics card to the latest version to fix it. The best way to update the driver without any hassle is to use a driver updating tool like Advanced Driver Updater. To use it, follow these steps:
Now check the Windows 11. The night light should be working.

The HDR feature is used in Windows to make pictures look vibrant. However, sometimes, this feature interferes with Windows 11 Night Light, and the PC doesn’t wake up from Sleep mode. Hence, we suggest toggling the switch off and on to fix the issue.
Now check the night light issue; it should be fixed.
If the above methods did not help, we suggest changing the Windows Registry to get Night Light mode working.
If you are unsure about making changes to the registry, please take a backup of the Windows Registry. Once you have the backup, follow the steps to make changes to the registry.
HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > CloudStore > Store > DefaultAccountCloud > Cloud

Select Delete.

You've forgotten to ask one of the most important questions about Night Light (or any other display settings, for that matter) not working: Is the computer connecting via a docking station? If the answer is yes, than 99.9% of the time that's the cause of the display problem. Docking stations are great--but they have their own drivers that can severely limit the functionality of the computers settings, or make them unusable entirely.
If you're using a Docking Station -- disconnect it and connect your computer directly to the monitor with the appropriate cable. If that doesn't work, then go ahead and try the more in-depth troubleshooting. But do that first to avoid unnecessary pain and frustration!
Hello Sir/Mam,
We appreciate your input and will add it as a note.
Thanks and Regards
Yep, mine was the docking station. At first, though I disconnected & reconnected it before and after rebooting, it still didn't work on the monitors or the laptop itself.
I was about to start fiddling with the registry when I decided to try all the methods at the same time.
I disconnected the docking station, then rebooted, then got it working on the laptop alone first, then reconnected the docking station & it started working again as normal.
Hello Sir/Mam,
We are glad to know that your problem is fixed.
Thanks and Regards
I had this problem, you need to make sure you are logged into your microsoft account, then the night light options will work again.
Hello Edward

We will add this point in the post.
Thanks and Regards
