How to Disable Task Manager on Windows 10

Want to block users from opening the Task Manager? This article shows you how to disable the Task Manager in Windows 10 and 11.

Task Manager is one of the most useful applications in Windows. As most of you know, the Task Manager gives you a wealth of information about the system, running processes, startup applications, and more. One of the most common use cases for Task Manager is closing unresponsive applications and managing startup applications.

As useful as it is, in some cases, such as in professional and office settings, you may want to disable Task Manager so that no one can use it. If this is the case, follow these instructions to disable Task Manager in Windows.

Note: Only disable the Task Manager when it is necessary and if you know what you are doing. Blocking or disabling Task Manager might be inconvenient for you and other system users. This is especially true in educational settings, where students are sometimes forced to exit apps such as dev tools using the Task Manager.
