How to change the value of HungAppTimeout in Windows 10

If the application (task) does not automatically end (close) when you restart, shut down, or log off from Windows 10, the system will wait 5 seconds ( HungAppTimeout ) by default before the End Task dialog box appears, requires you to cancel or close the listed applications and restart, shut down or log out at all costs.

If you do not make a selection in the End Task dialog box before the 1 minute expires, Windows 10 will automatically cancel the reboot, shutdown or logout by default.

HungAppTimeout also specifies the time (5 seconds by default) the system waits for the user process to finish, after the user clicks the End Task task button in Task Manager. If this threshold is exceeded, the End Task dialog box appears, indicating that the process is unresponsive.
