After upgrading the OS to windows 10, the fn keys (f9 and f10) for adjusting the screen brightness are not working. I have already updated the driver of the keyboard to the latest version and there is no problem in ajusting the screen brightness in the display setting panel. Please help.

Welcome to HP Forums, this is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out :)
As I understand the Fn keys to increase or decrease the brightness isn't working and you need a way to fix this issue,
Here's is a post related to the same concern you have, I suggest you check this as well: Click here
It's good that you've already re-install & updated the system event utility driver as that's the most common interface for the function keys, however, there are a few other things you do as well,
Starting with updating the video adapters using the device manager and/or the HP Support assistant
Click the Start button, then click Run .
2.In the Run window, next to Open , type MSCONFIG .
3.Press the ENTER key.
4.In the System Configuration Utility window, click the Startup tab.
5.On the Startup tab, under Startup Item , ensure that there is a check in the HKserv checkbox.
NOTE: If HKserv is missing, reinstall the HotKey Utility application by clicking here
Let me know how that pans out,
I hope you have a good day ahead,
