Tip #1: Brightness increment/decrement HID usages only operate only on Mobile systems (battery powered) and require Windows 8. Free software to adjust the brightness of a computer screen. Hardware should only send an input report when button is pressed down and another when the key is released. Hardware should not keep resending the usage when these keys are kept depressed by user.

Brightness up/down are retriggering keys and their rate of repeat is handled by Windows.

Click on Update driver from the context menu. Go to Device Manager, expand Display adapters, and right-click on the display driver. When a new usage is sent, it is assumed that the usage for the previous key is released. One of the ways to fix the Windows 10 brightness slider missing issue is to update display driver software with the latest stable version. Follow the steps provided below for ease: Open Settings and then click on System, just as shown in the previous solution. Consumer controls do not allow multiple buttons to be pressed simultaneously. You can change these settings and fix the bright slider not working issues on Windows 10, 8, and 7.

Only one usage is active and sent at a time.

When the key is released an input report with usage value=0 is issued.

When a user presses a key, an input report is generated to identify the key.

I reccently switched from windows 7 to windows 10 and found out that the driver version provided by windows update (9.) doesnt let me change brightness (neither with hotkeys or windows slide). If I install a fresh copy of Windows 7 on it, then none of the Sound/Brightness/SD Card slots/Touchscreen/Video functions work 'out of the box', and it is necessary to visit the HP website, look up my particular model and then download all of the drivers required. These HID usages operate only on mobile systems (battery powered) and require Windows 8.
