I work late nights because most of the users for the web apps I develop are in Tier 1 countries, which have a completely different time zone from mine. To make things easier, I prefer using dark mode when working at night. However, the brightness of my laptop still causes me headaches sometimes. To avoid this, I always lower the brightness while working.

Out of curiosity, I looked into different ways to adjust brightness and found that there are more than 8 + methods to change brightness on Windows 11. Let’s dive into these methods and I will recommened you to find the Windows Features.
