The Task Manager is a powerful Windows 11 utility that provides detailed real-time information about the software and hardware on your PC. It’s also indispensable when troubleshooting applications, monitoring hardware resource usage, and managing startup programs.
In this in-depth guide and overview, you’ll learn everything you need to know about the Task Manager in Windows 11, including ways to use it effectively.
Opening the Windows 11 Task Manager
In Windows 11, you can launch the Task Manager just like any other program by selecting 開始 > 全てのアプリ > Windowsツール > Task Manager. However, the most convenient way to invoke it is through the Power User menu (right-click the 開始 ボタンを選択 Task Manager).
If you prefer keyboard shortcuts, pressing Ctrlキー + シフト + Escキー will quickly bring up the Task Manager. If the operating system appears stuck, you can still get to it by pressing Ctrlキー + 他の + 削除 (which opens Windows 11’s Security Screen) and then selecting Task Manager.
The Default Task Manager
The Windows 11 Task Manager appears as a stripped-down version of the full user interface by default. It’s tiny, features no menu options, and simply shows a list of active apps on your computer.
You can choose any app within the list and forcibly shut it down by selecting the 終了タスク button. That’s the quickest way to quit unresponsive programs.
Right-clicking any app within the list also reveals multiple contextual options as follows:
- 切り替える: Immediately brings the app into focus.
- End task: Forcibly shuts down the app. It’s the same as selecting the 終了タスク
- フィードバックを提供します: Provide feedback to Microsoft.
- ダンプファイルを作成する: Generate a dump (.DMP) file of the program, which is often requested by support engineers for troubleshooting purposes. You can also analyze dump files yourself.
- Run new task: Launch a new program, folder, or document with or without elevated privileges in Windows.
- 常にトップに: Place the Task Manager on top of other apps. This option also works in expanded view, which then helps you track resource usage in real-time.
- 詳細に行く: Automatically select the executable file related to the program within the Details tab in the expanded view.
- 開いているファイルの場所: Opens the directory of the program’s main executable file in a File Explorer window.
- オンラインで検索: Perform an online search using Bing. If you don’t recognize a program, use this option to learn more about it.
- プロパティ: Brings up the program executable’s Properties dialog box. You can then check or modify its general, compatibility, and security settings and view additional details such as the version, publisher, etc.
The Expanded Task Manager
