By default, such applications are automatically terminated if they attempt to cancel shutdown or block it indefinitely. - If you enable this setting, console applications or GUI applications without visible top-level windows that block or cancel shutdown won't be automatically terminated during shutdown. - If you disable or don't configure this setting, these applications will be automatically terminated during shutdown, helping to ensure that Windows can shut down faster and more smoothly. > [!NOTE] > This policy setting applies to all sites in Trusted zones. **Description framework properties**: | Property name | Property value | |:--|:--| | Format | `chr` (string) | | Access Type | Add, Delete, Get, Replace | [!INCLUDE [ADMX-backed policy note](includes/mdm-admx-policy-note.md)] **ADMX mapping**: | Name | Value | |:--|:--| | Name | AllowBlockingAppsAtShutdown | | Friendly Name | Turn off automatic termination of applications that block or cancel shutdown | | Location | Computer Configuration | | Path | System > Shutdown Options | | Registry Key Name | Software\Policies\Microsoft\Windows\System | | Registry Value Name | AllowBlockingAppsAtShutdown | | ADMX File Name | Winsrv.admx | ## Related articles [Policy configuration service provider](policy-configuration-service-provider.md)
