Hi!

I recently had to hard reset my AN517-52 and now I've reinstalled Windows 11, but I have run into multiple Problems like Bluetooth drivers missing (fixed), generally really low framerate in Chrome, Windows and etc., and also no control over brightness (neither a slider nor the fn + right/ left).

I was wondering if anyone here knew the solutions to the latter problems or knew how to reset the Laptop to the Windows it came preinstalled with.
