HP Hotkeys – Troubleshooting Notes (DriverFiles)
People arrived here assuming HP Hotkeys had broken after updates because specific keys stopped behaving while others still worked. This page documents what actually happened when that assumption was tested. In practice, service behavior, update timing, and model differences mattered more than the driver alone, and some fixes traded one problem for another.
Problem: Brightness and mic keys trigger HP Hotkey errors
What users observed: Pressing brightness or microphone keys stopped adjusting anything and instead opened a small HP Hotkey Support window. Other function keys continued to work, which made the failure feel selective and confusing.
What was tried: Reinstalling HP Hotkey Support did not change the behavior.
Where this sometimes ended: The error window stopped appearing after a service related to HP Hotkeys was disabled and the software was reinstalled. In some cases, the keys resumed working normally.
Problem: HP Hotkey Support window pops up on brightness change
What users observed: Every brightness adjustment caused a pop-up labeled HP Hotkey Support. The keys still responded, but the interruption made normal use frustrating.
What was tried: Attention shifted away from the driver itself toward background services tied to Hotkeys.
Where this sometimes ended: Disabling the associated Hotkey service stopped the pop-up while leaving the function keys operational after reboot.
Problem: Fn key stops working after Windows update
What users observed: Following a system update, the HP Hotkey Support pop-up appeared and Fn-based controls failed. The timing suggested a driver regression.
What was tried: Reinstalling a specific HP Hotkey package was attempted after changing how the Hotkey service started.
Where this sometimes ended: The error message disappeared, but reports noted that brightness controls did not always return. The fix removed the symptom without consistently restoring function.
Problem: Alt keys stop responding - media key appears
What users observed: Both Alt keys on the laptop stopped registering, while an external keyboard worked normally. Random key presses triggered a Media Play/Pause signal, even when unrelated keys were pressed.
What was tried: Browser-level changes were made earlier for an unrelated issue, but no clear Hotkey change resolved the keyboard behavior.
How this played out: No definitive resolution was recorded. The abnormal key mapping persisted, and the link to HP Hotkeys remained unclear.
Problem: HP Hotkey crashes on volume change
What users observed: Adjusting volume caused the Hotkey process to consume excessive memory and crash. Attempts to install an alternative package failed with a compatibility error.
What was tried: General reinstalls and update checks were attempted, with mixed results.
Where this sometimes ended: Some systems stabilized after reinstalling the utility, while others continued to show instability.
