Windows 10: Night light not firing on schedule time AGAIN in Win11

After fiddling with this feature on Windows 10 numerous times, uninstalls, reinstalls etc to finally resolving it somehow not sure how for good, I have now faced the exact same issue in freshly / clean Windows 11 install.Absolutely the same - the scheduled time approaches and night light won't activate unless I log off/on or restart in that time.Can Win developers actually fix this rather simple feature and if there's a thing to try, some registry fix, I'd be more than grateful.Using latest AMD graphic card drivers for 5500XT GPU and latest W11 install.

Night light schedule not working

Hi,

Thank you for writing to Microsoft Community Forums.

We understand your concern as you are unable to schedule the time for Night Light feature in Windows 10. In order to get clarity and to assist you accordingly, please reply with the answers to the questions below.

• What is the Windows 10 version and Build installed? (Type
  winver in Windows search/Run command)
  
• Are you aware of any changes, prior to this issue?

Meanwhile, we would suggest you to update the display driver from Device Manager.

1. Press Windows + X and select
   Device Manager.
   
2. Scroll down and expand Display Adapters. Now Right click on the display devices and select
   Update Driver.
   
3. Select Search automatically for updated driver software.
   
4. Select Update Driver.
   
5. Restart the PC and check

If the issue persists even after updating the driver, then we would suggest you to make the below registry change.

1. Press Windows +R key to open
   run command.
   
2. Type regedit and click on
   Ok.
   
3. Navigate to this location: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount
   
4. Here, delete the following sub keys
   
   1. $$windows.data.bluelightreduction.bluelightreductionstate
      
   2. $$windows.data.bluelightreduction.settings
      

Note: Important this section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow
these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Follow the steps to take backup of registry

After deleting the registry sub keys, restart the PC and then enable Night Light feature from Windows settings.

Let us know how it goes.

Night Light/Dark Mode Task Scheduler

What I'm trying to achieve is really quite simple.

I want to create 2 tasks:

1. When I turn on the night light, dark default app mode is enabled
2. When I turn off the night light, light default app mode is enabled

I don't really have any experience with creating tasks in Task Scheduler so I'd appreciate some pretty in-depth help

Thanks
