Short answer

Updated Oct 8, 2026

Windows 11 can show 'End task' when you right click an app on the taskbar, which closes a frozen program without opening Task Manager. TaskbarEndTask set to 1 switches it on. In the registry it sets TaskbarEndTask to 1 under HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\TaskbarDeveloperSettings.
