Additional Information

Instead of manual registry editing to lock the task manager, you can run the command line on behalf of the administrator and enter the command (after entering Enter):

REG Add HKCU \ Software \ Microsoft \ Windows \ Currentversion \ POLICIES \ System / V DISABLETASKMGR / T REG_DWORD / D 1 / F

It will automatically create the desired registry key and add a parameter responsible for shutdown. If necessary, you can also create a REG file to add the DisableTaskmgr parameter with 1 to the registry.

If in the future you will need to re-enable the task manager, it is enough or disable the option in the local group policy editor, or delete the parameter from the registry, or change its value to 0 (zero).
