Ultimate Guide to Fix Brightness Slider Missing in Windows

Usually, the brightness slider can be found in Windows Display settings under the Brightness and Color section. Its absence indicates a system problem that impacts desktop and laptop computers with inbuilt displays. Such problems are usually triggered by faulty updates, system changes, or incorrect driver installations.

The primary cause of Windows’ lack of a brightness slider is outdated or incompatible display drivers.
The system might not recognize display settings if the driver for your display adapter isn’t appropriately installed or updated, which would make the brightness control disappear.

In correct drivers and other issues might trigger other Windows UI elements missing (learn how to solve it here) as well as “D:” drive missing and not-visible Bluetooth icon.
