After Windows update to 20H2 19042 the brightness option has been disappeared completely. The F2 and F3 keys are not functional, neither brightness adjustment available in the Windows Notifications center. A few days of research, drivers reinstallation, removing, etc. was not helpful. The Intel Graphics Command Center is perfectly working, no errors shown, no updates are available, but no brightness option is available anywhere. Any suggestions will be very appreciated.
Use the driver provided by HP, and test.
