I had the same exact issue on the same product when I upgraded to Windows 11 yesterday. I had to go back to Windows 10 because it kept crashing my computer. On Windows 10 it barely uses any of my RAM. Does anyone know how to fix this? Is it a glitch or bug with Windows 11 on the HP Zbook 15?
I've noticed the same problem here after upgrading to 21H1 today. The problem does not seem to occur where I delay the startup of the HP Hotkey UWP Service. I'm not sure, if these are proper workarounds but you might try this:
I changed the startup of the "HP hotkey uwp service" to Manual and that seems to have temporarily fixed the issue. I hope they come up with a permanent fix. (Control Panel > Administrative Tools > Services)
So glad I found this post! I have the same issue with my ZBook 15 G5. When I started up the laptop in the morning I first observed that the fan was running rather hard, suggesting lots of CPU usage. I didn't think much of it until my display froze up and I got an "out of memory" message. I rebooted and my display driver was messed up, no longer recognizing my 2 external displays connected via the HP Dock. Checked HP Support for updated display driver, updated the driver, and all seemed well. But the runaway memory continued after rebooting. That's when I found this post and set the HP Hotkey UWP Service to "Manual". So far, so good. Hopefully there will be a fix for this so that my hotkeys will work properly again.
