Windows 10: Change the increments by which you can adjust the display brightness.

Hello. My keyboard has Fn + keys to increase or decrease the display brightness by 10%. I wonder if there's a way to reduce that percentage, as the (10%) change can be too drastic in a dark room.

I tried this, but it didn't work:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\monitor\Parameters
'MinimumStepPercentage' 1

Thank you.

:)
