Re: Not able to adjust screen brightness after Windows 10 upgrade

On Toshiba's site for any Satellite Pro model, I'm only seeing drivers up to Windows 8.1. Have you tried reinstalling the Windows 8.1 drivers over Windows 10? This could work or you could wait for Windows 10 drivers to be released if the PC is fully compatible with the drivers manufactured.
