Night light turns on after powering on

Hi,
I have windows 11 pro in my laptop. It is dual booted with ubuntu 24.04 . Whenever I start my laptop and open into windows, night light turns on automatically, even though the setting 'night light' is turned off. The night light will be off for a second in pass word window, after that in the pass word window itself, the night light will turn on. After that, if I go to the setting of 'night light' or open the quick access settings on bottom right corner, then night light turns off automatically. The setting 'night light' will be turned off throughout this process. Also the 'night light schedule' is turned off in both ubuntu and windows. In ubuntu, there is no problem with night light.

Any help is much appreciated.

    Thank you so much for update. The Next step is Reset Night Light Settings in the Registry

    There’s a known bug where Night Light state gets stuck, even if the setting says it’s off.

    Here’s how to fix it:

    Press Win + R, type regedit, and hit Enter.

    Go to this path:

    pgsql

    Copy

    Edit

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount

    Delete any keys that look like:

    $$windows.data.bluelightreduction.bluelightreductionstate

    $$windows.data.bluelightreduction.settings

    Restart your laptop.

    (Tip: Back up your registry first, just in case.)

    Let me know what happened after this and I will guide you further.

    Regards

    Udit

    Hello Sinan,

    Thank you for reaching out, I am Udit and I am glad to assist you today.

    To fix this night light issue please follow these steps.

    1. Go to Device Manager > Display Adapters > Right-click your graphics card > Update driver.

    Even better, visit the official website (Intel, NVIDIA, or AMD) to download the latest driver manually.

    1. Go to Control Panel > Power Options > Choose what the power buttons do.

    Click Change settings that are currently unavailable, then uncheck Turn on fast startup.

    Save and restart.

    1. Sometimes Night Light uses your location to adjust lighting automatically, even if scheduling is off.

    Go to Settings > Privacy & security > Location.

    You can either turn off location completely or at least prevent the system from using it for display settings.

    Let me know how it goes after applying these steps.

    Regards,

    Udit.
