If you’re a night owl, don’t forget to enable Night Light on your Windows computer. This option emits a warmer yellowish light that helps you fall asleep faster after shutting your computer down. As a quick reminder, the standard blue light that most screens emit may suppress the body’s melatonin release. This means you’re more likely to have a hard time falling asleep.
Unfortunately, the Night Light option is sometimes greyed out in your Windows settings. If you already restarted your device, but the issue persists, follow the steps below to solve the problem.
What to Do if Night Light Is Greyed out on Windows?
Delete Blue Light Reduction in Registry Editor
There are two ways to enable Night Light on Windows. You can either click on the Action Center and select Night Light or toggle on the option under Settings → System → Display.
However, delete the blue light reduction entries from the Registry if these two options are not available.
- Type regedit in the Windows Start search field.
- Double-click on the Registry Editor to launch the app.
- Then navigate to the following path:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount
- Delete these two entries:
default$windows.data.bluelightreduction.bluelightreductionstatedefault$windows.data.bluelightreduction.settings
- Then restart your computer, and check if Night Light is working.
Create a Night Light Script
Alternatively, you can also create a .reg script that you can run to automatically fix the issue.
- Open a new Notepad file.
- Then paste the following instructions into the blank file:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$$windows.data.bluelightreduction.bluelightreductionstate] [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$$windows.data.bluelightreduction.bluelightreductionstate\Current] "Data"=hex:02,00,00,00,54,83,08,4a,03,ba,d2,01,00,00,00,00,43,42,01,00,10,00,\
d0,0a,02,c6,14,b8,8e,9d,d0,b4,c0,ae,e9,01,00- Save the file to your desktop and name it NightLightFix.reg
- Note: You need to use the .reg extension to ensure the Registry Editor can recognize and run the script.
- Double-click on the NightLightFix file to run the script. Check if you can enable the Night Light option.
Update Your Display Driver
Additionally, make sure to update your display driver to the latest version.
- Launch the Device Manager.
- Expand the list of Display Adapters.
- Right-click on your graphics driver and select Update driver.
- Restart your computer and check if the issue persists.
Conclusion
If the Night Light option is greyed out on your Windows computer, update your display driver to the latest version. Then launch the Registry Editor and delete the blue light reduction entries. Alternatively, you can also create a .reg script to automate the whole process. Did this guide help you fix the problem? Let us know which of the above solutions worked for you. Comment down below.

I found the solution (for my PC at least) in Windows 10! So it appears my sister wanted to create a new microsoft account from the settings app (Settings–>Accounts–>Email & accounts) which she couldn’t in the end and was left like this without ever signing in and a warning from notifications was popping up, that i had to fix my microsoft account (which it was referring to my sister’s microsoft account and not mine) and it was interfering with my account’s settings and i had to fix it. So i went to Email & accounts and i deleted my sister’s, since she failed to create a new one, and it instantly fixed on its own! Also, settings app was crashing for no reason always and my pc was kinda lagging for no reason as well and i have a very good pc! So try to delete any microsoft account that you are NOT using and DONT NEED or CONFIRM the existing account by connecting with your password and you are good to go!

what a waste of bandwith

If none of these things worked for you, I just found a program “f.lux”, works a treat!

As with the others, reg files weren’t there to be deleted, making .reg file did nothing, and drivers are up to date. Not sure if others have had this, but this came after my laptop started up and logged into a TEMP account, and problems have continued since then.
Jinx says
.reg fixes didn’t help me
reinstall of drivers after DDU didn’t help me
common searches didn’t help, had to specifically search services associated with night light and found that these need to be running/enabled
I seemingly disabled network connection broker at some point
(i have the following automatic(delayed), automatic, manual)
– Connected Devices Platform Service (CDPSvc)
– Connected Devices Platform User Service_##### (CDPUserSvc_#####)
– Network Connection Broker (NcbService)
where ##### are random hex characters

Went to attempt the deletion fix; was not an option because they weren’t even there to begin with, so I went ahead with creating the registry fix option…still did not work…and everything else is up to date.
In short, I’m in the same boat as Keisha…and I’m so mad…
Keisha says
Did all of the recommended steps. The two items you recommend deleting on the registry editor are not even available options. Made the NightLightFix.reg file….still greyed out. Checked my drivers…they are up-to-date. Frustrating.
