Your screen brightness keeps changing by itself
Windows has an automatic brightness feature that adjusts the screen based on room lighting or what's on your screen. Turning it off takes less than 5 minutes and gives you back control.
Windows includes automatic brightness control that watches either the light in your room or what's on your screen and adjusts brightness without asking. You can turn this off and set brightness to your preference permanently.
