How To Disable Windows Task Manager Using Registry

Note: If you are looking to enable your task manager if it got disabled by your administrator or some virus, then have a look at this post. This tip is for disabling your task manager, not enable it.
Sometimes one needs to disable the task manager to give clients limited access in a network or to prevent other users from doing a specific task. There are multiple software available for this purpose, but the best way is to disable it using Local Group Policy Editor which is build-in your Windows and does not require any software to be installed.

To begin with you will have to open Local Group Policy Editor, to do this go to Run and enter gpedit.msc.
 
Now navigate to User Configuration > Administrative Templates > System > Ctrl+Alt+Del Options as shown in the screenshot below.

Now simply double-click on Remove Task Manager and you will see a dialog box, select Enabled and click OK as shown below.

Now you will see your Computer’s Task Manager has been disabled. To enable it back, select Not Configured. That’s it, wasn’t it simple.
