Disable Access to the Task Manager

There is a simply way to disable access to the task manager.

1. Open a new text file or notepad to type the following sentences.
   Note: There is a line without anything behind the last sentence.
   Windows Registry Editor Version 5.00
   
   [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
   "DisableTaskmgr"=dword:00000001
   
   The following image shows these sentences.
   
   
2. Click File -> Save as to save this file. You can save it to any location. Then type "Disable TaskMgr.reg" in "File name", and select "All files" as the save type. Finally click on "Save" button.
   
3. Then you will see a Registry file in your desktop.
   
4. Double-click this file, and you will see the following tips box, and click "Yes" button.
   
5. Then the key and values have successfully added to the registry. Moreover when you right click on the taskbar, you will find the "Start Task Manager" disabled.
   
   

If you want to use Task Manager again, just change the registry file you wrote before. Change the value from 1 to 0. In other words, you change the last line to "DisableTaskmgr"=dword:00000000.
