HP Hotkey UWP Service is eating up memory on some Windows 11 laptops


Some laptop owners upgrading to Windows 11 are reporting that a utility from HP is consuming huge amounts of RAM, to the point that systems are rendered unusable.
The utility in question is the HP Hotkey UWP Service which is used to control the Fn key on HP laptops. While the software functioned well under Windows 10, upgrading to Windows 11 results in huge resource usage. Affected users are asking whether there is a problem with Windows 11, or with their laptop, but it would seem more likely that a memory leak is to blame.
