How to disable adaptive brightness on Windows 10 when everything else fails

So, the story is short. I have installed Windows 10 via Bootcamp on my 2015 Macbook Air, but the screen changes the brightness randomly from low to high. I have tried the simplest solution to disable adaptive brightness by unchecking the following option:

Windows -> Display settings -> Change brightness automatically when lighting changes (disable)

No success. After that, I have tried to disable the Adaptive Brightness from Power settings option from Power plan settings:

Control Panel > Power Option > Current plan > Change Plan Settings > Change advanced power settings > Display > Enable adaptive brightness > Set to OFF for “On battery” and “Plugged in” option.

Still, my brightness was having its own will. Finally, I have managed to find a solution for the problem. There was another hidden and easy to miss option enabled on my Intel HD Graphics app.

So, here are the steps to finally disable this annoying option:

  1. Open Windows Start and search for ‘Intel’
  2. Select ‘Intel HD Graphics Control Panel’ from results
  3. Click on the ‘Power’ icon – mine was a battery icon
  4. Click ‘On Battery’ tab on the left sidebar
  5. Find ‘Display Power Saving Technology’
  6. Select Disable for ‘Display Power Saving Technology’ and click Save/Apply

This did the trick for me! Let me know if it works for you. Also, you should disable the adaptive brightness from display settings and power plan settings.
