Last Updated: Jan 19, 2024 by

If you’re someone who spends a lot of time on your computer, you may have noticed that your screen can become quite bright and harsh on your eyes, especially at night. This is due to the blue light emitted from your screen, which can disrupt your sleep patterns and cause eye strain. Luckily, Windows 10 has a feature called “night light” that can help reduce the amount of blue light emitted from your screen. However, by default, this feature is set to automatically turn off at sunrise. In this article, we’ll show you how to keep night light always on in Windows 10, so you can protect your eyes and sleep better.

What is Night Light?

Before we dive into how to keep night light always on, let’s first understand what it is. Night light is a feature in Windows 10 that reduces the amount of blue light emitted from your screen, making it easier on your eyes and helping you sleep better. It works by shifting the colors on your screen to warmer tones, similar to the colors of sunset. This can also help reduce eye strain and headaches caused by prolonged screen time.

How to Turn on Night Light

To turn on night light on windows 10, follow these steps:

  1. Click on the Start button and go to Settings.
  2. In the Settings menu, click on “System.”
  3. In the System menu, click on “Display.”
  4. Under the “Color” section, toggle the switch for “Night light” to turn it on.

Once night light is turned on, you can adjust the intensity of the warm colors by using the slider under “Color temperature at night.” You can also schedule night light to turn on and off at specific times by clicking on “Night light settings” and adjusting the schedule.

How to Keep Night Light Always On

By default, night light is set to turn off at sunrise. However, if you want to keep night light always on, you can follow these steps:

  1. Go to the Start menu and search for “Task Scheduler.”
  2. In the Task Scheduler, click on “Create Basic Task” on the right-hand side.
  3. Name your task and click “Next.”
  4. Select “When I log on” and click “Next.”
  5. Under “Action,” select “Start a program” and click “Next.”
  6. In the “Program/script” field, type “reg.exe” and in the “Add arguments” field, type “add HKCU\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\DefaultAccount\Current\default$ /v f.lux.exe /t REG_DWORD /d 1 /f” and click “Next.”
  7. Click “Finish” to complete the task.

This will create a task that runs every time you log on to your computer, keeping night light always on.


If you’re having trouble keeping night light always on, try updating your graphics card drivers or resetting your display settings. You can also try using a third-party app, such as f.lux, which offers similar features to night light.
