I'm using HP Probook 440 G4 for last 3 months. And I couldn't increase/decrease brightness using Fn+F5/F6. Every time I tried, it said something like this.
[Window name] HP Hotkey UWP Service
Error: HP Software Framework is not installed in the system
Please download and install from the link -
Note: Restart system after installation
The link suggested here is not valid anymore. What can I do?
