The Windows Task Manager, Is native to the Windows platform and Is a very useful utility to both perform and monitor an array of tasks on your computer. For Instance, you can view all active processes running In the background, and terminate those that you don't need. This also means that anyone with physical access to your PC, can do the same and a lot more. In this tutorial, I will demonstrate how to completely disable Windows Task Manager.
Before I make a start, here's a snippet of Task Manager running on my Windows 10 Enterprise operating system. You can see all running processes and they can be killed with a few clicks of the mouse. Of course, there's a lot more that can be achieved, but It's not possible to cover the lot.
To disable Task Manager In It's entirety, I will be using the good old Group Policy Editor, that's only available on Windows 10 Pro, Enterprise and Education editions. If you're running Windows 10 Home edition, then you're out of luck.
Essentially, after applying the setting, each and every method used to try and access Task Manager, will fail. So let's rip Into this tutorial.
To access the Group Policy Editor, open the Run menu, enter gpedit.msc and hit OK.
The Group Policy Editor window will now open, so navigate to the following directory:
User Configuration > Administrative Templates > System
Then on the right pane, click on:
You will now see Remove Task Manager, so double-click It.
To the left of the window, click the Enabled radio button and to finalize the process, hit OK.
Let's try and access Task Manager. Open the Search bar, enter task manager and click on the search result accordingly named as such.
And here's the result. As you can see, the Windows Task Manager Is disabled.
Irrespective of the methodology used to try and access the Windows Task Manager, be It right-clicking on the Taskbar, using Ctrl+Alt+Del on your keyboard or as per the above example via the Search bar, the moment this setting Is applied, It cannot be accessed.
The Windows Task Manager can also be disabled, by editing entries In the Windows Registry, but the good thing about the Group Policy Editor, Is that It's a lot safer and the change takes effect Immediately without the need to reboot your PC.
To go back to It's original state, refer to Step Four above, select the Not Configured radio button and then click OK.
