HP Hotkey Support Solution

[flyingfish35]

I was having issues with my brightness keys not working and getting the "HP Hotkey Support" popup for each f3/f4 key press. After reading every forum answer I could find and messing around for 2 days, I finally found a solution that works for me so I thought I'd share in case anyone else finds it helpful. I'm using Elitebook 830 G5 running Windows 10.

Solutions that did not work for me:

• Installing CASLSetup.exe (link from this answer: Solved: Re: HP hotkey support missing - HP Support Community - 8198988  ). I checked Services and it was already installed, but I tried reinstalling anyway just in case.
• Installing the correct driver for my device: HP Drivers > select device & OS > Driver-Keyboard, Mouse and Input Devices > HP Hotkey Support - UWP. (Same as above, was already installed but tried again)
• Installing the update from Update HP Hotkey UWP Service - HP Support Community - 8356241  
• Installing HP Support Assistant | HP® Support  and installing all recommended updates
• Installing HP PC Hardware Diagnostics Tool and running the Image Assistant

What did work for me:

1. Installing HP Hotkey Support - CMIT (sp91903) (link from this answer),  even though the driver is intended for a different laptop. At this point, the brightness keys were now functioning, but I was still getting the pop-up for each key press. When I checked Services, there was an additional service added: the original "HP Hotkey UWP Service" and the new "HP Hotkey Service". I confirmed that the UWP service was the issue as stopping it stopped the popups, though it restarted on the next device reboot.
2. Stop the pop-ups. There were two options that worked to do this. Personally I chose to do both as it seems like the UWP service has had some issues with memory leaks in the past (see the update link above) and I'd rather not run extra software I'm not using, but I'm not sure whether it makes much difference. Someone more knowledgeable might have a better answer for that.
   
   1. Roll back keyboard driver: Open Device Manager (search for it in the Windows taskbar) > Keyboard > right click the keyboard type > Properties > In Driver tab, click "Roll Back Driver". For me it was originally called "Standard 101/102-Key or Microsoft Natural PS/2 Keyboard for HP Hotkey Support" and after rolling back it was just called "Standard PS/2 Keyboard".
   2. Disable UWP service from automatically starting on device restart: In Services (again, Windows taskbar), right click "HP Hotkey UWP Service" > Properties > In General tab, change "Startup type" to "Disabled" > apply.
3. Restart the laptop to apply changes

Hope this helps!

Same here! It works perfectly well for me too!

OMG thanks !

For my Zbook 17 G3, the SP95527 did the trick. But I still had the error message popups. Just deactivating the HP hotkey UWP Service solved the issue !

Works for me also for HP Elitebook 850 G5, Windows 10 64bit 22H2

Seems big part of the solution is this https://ftp.hp.com/pub/softpaq/sp91501-92000/sp91903.exe

The HP UWP Hotkey Service is a mess, I disabled it.
Couldn't find a way to uninstall it 😞

It workes on my Elitebook 850 G5 running Windows11. I did also try first solution, didnt work. With solution two, now the hot keys is working (brightness and microphone). I did not rollback the keyboard driver, because that was not possible. Disable former HP hotkey service i did to finish the strange error-message. Now it is well.
Thanks from Bamberg
