    So I upgraded to creator update and tried the night light function once and it worked. Today it is greyed out and can not be enabled, anyone had this issue?

    :)

  6. It might be a driver related issue, make sure, you have all drivers updated, particularly GPU.

    You can try f.lux to see, if the driver still allows you to change colour's warmth.

    Yeah I can't install the driver (see this post). I suspect a lot of people have the same problem.

    I had this. It is a driver issue. It doesn't work with the graphics drivers that are installed via Windows Update. You need to install the driver direct from the manufacturer.

    for me it started working again after joining insider slow and installing the update. it also installed a new intel graphic driver.

    It was likely the new graphics driver that helped.

    below solution worked for me. i dont guarantee that it is safe or it will work for anyone else.
    you should know what u r doing


    delete the below keys, i deleted all that folder
    you can right click export just in case you regret it later


    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.settings


    also search using f3 for bluelightreduction and bluelightreductionstate. you may find it in hkey_user, i also deleted those. i had one of each

    now logout then login or just restart ur pc/laptop


    best

    Hello, i found solution.
    Just put this content in a '.reg' file. (example: recover.reg)



    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 and execute to recover Night Light Default data

    I have tried night light and think it still needs work when scrolling it changes to dark and light, very peculiar on the eyes I have it switched off for now anyway.
