In addition, pressing the play/pause, next or previous buttons also does not summon the Windows media popup. Perhaps there is an extra driver that is blocking these signal from being picked up? It is not possible to use a system restore point by the way.
Model: Dell XPS 15 9550Windows 10 I made the mistake of trying to update drivers with the program ‘Snappy Driver Installer’. It changed a lot of drivers. The problem is that the the ‘media keys’ — the keys on the function row, F1-F12 — no longer work normal. This shows itself in 4 ways: It is clear that some wrong driver causes the problem. Perhaps a driver that should never be updated. My question is, what (type of) driver is responsible for the function/media keys? Somewhere in between keyboard and display? The keys do work, but the response to pressing them is different. No more popups, and no more smooth brightness toggling. What drivers controls this specific functionality? If someone knows, I can try to download an older version of it.
What driver is for media and brightness keys on XPS 15 9550?
