The genuine QLBController.exe file is a software component of HP Hotkey Support software. The HP HotKey Support (HPHKS) software provides the support for handling the Hotkeys.

There can be multiple reasons for the error on Windows 10, but the two of the most common reasons are interference of third-party applications and missing or corrupted driver. However, we have gone through all the possible fixes for the same.

First, ensure that all your HP drivers & firmware are updated. It is best to use HP Support Assistant to update drivers and firmware.
