The User Process alert triggers when a desktop application performance issue occurs.

If your desktop is not responsive due to processes taking time or memory resources, and you cannot perform a clean shutdown, you can initiate a Power Off command to forcibly stop the running virtual machine.

End the process, or if you have a non-persistent desktop, log off and log back in to get a new desktop. If you have a persistent desktop, power off and restart the desktop to clean up all running processes.
