Change laptop screen brightness?

After the driver updates, changing the screen brightness no longer works on the laptop.

Does somebody has any idea?

The controller no longer exists and even with FN + key combination, which otherwise always worked, no longer works.

This is the case on two different laptops.

Microsoft decided at some point that you no longer need it - for a while there was a patch that no longer works.

But there's a program with which you can dim - you have to google it.
