How to Change the Value of HungAppTimeout in Windows 10

This guide explains how to change the Value of HungAppTimeout in Windows 10, with clear steps, practical tips, and important checks before you begin.

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.
