You can query this particular window state via the IsHungAppWindow() API.ĭetection is only the first step. If a message has not been retrieved within 5 seconds, the DWM declares the window to be hung. The operating system detects this state by attaching a timer to pending messages in the message queue. If the thread does not service the queue by calling GetMessage(), messages are not processed, and the window hangs: it can neither redraw nor can it accept input from the user. The thread retrieves and dispatches those messages via its message queue. The DWM posts messages (keyboard/mouse input and messages from other windows, as well as itself) into the thread-specific message queue. When an application (or more accurately, a thread) creates a window on the desktop, it enters into an implicit contract with the Desktop Window Manager (DWM) to process window messages in a timely fashion. Otherwise, the user might have to restart the machine in order to recover a hung application.

Windows automatically detects, collects debug information, and optionally terminates or restarts hung applications. However, an unresponsive UI is one of the most common hang experiences, and this scenario currently receives the most operating system support for both detection as well as recovery. There are many different root causes for application hangs, and not all of them manifest themselves in an unresponsive UI. Next to crashes, application hangs are the most common source of user disruption when working with Win32 applications. After 5 seconds, they will try to terminate a hung application. However, from user research, we know that users get annoyed and frustrated after just a couple of seconds of unresponsiveness. The application might be busy recalculating some data, or simply waiting for its disk I/O to complete. Users get impatient rather quickly when the application does not react in a timely fashion to their input.Ī programmer might recognize many legitimate reasons for an application not to instantly respond to user input.
When they save a lengthy document in their favorite word processor, they want to continue typing while the disk is still spinning. When they click a menu, they want the application to react instantly, even if it is currently printing their work.
