Bootcamp Windows 10 Brightness Not Working

Screen brightness not working in Bootcamp Windows 10 MBP late 2012 15' Mac I have a Macbook Pro 15' late 2012 running with bootcamp (mostly for light PC gaming) and with the new fall creators update for Windows 10, I have not been able to adjust the brightness of the screen, either using the FN+F2 shortcut, or using the built in windows screen. I am using windows 10 on bootcamp on macbookpro. While fiddling with quick settings corner, I ended up selecting 0% brightness. And now I cannot get screen to brighten. Its stuck at 0% and the macbook brightness control keys are not working with windows 10. My windows 10 is all dark and unusable. Turn Off 'Adjust My Screen Brightness Automatically' Setting; I hope this helps. If anyone is having problems with Windows 10 bootcamp, I would strongly recommend installing the most up-to-date bootcamp drivers. I lost my F-key functionality after the upgrade, and reinstalling the updated drivers resolved that issue. Not being able to change the brightness of your screen from the taskbar or the Notification Center is a big inconvenience for Windows 10 users as they would alternatively have to search for brightness settings deep inside the Settings app each time they have to change the brightness of the screen.
