If I exit the application via the taskbar, it requires a password, which is perfect for securing the application from unauthorized exit. But I realized that one can exit the application from the task manager without entering a password. Can you please add this feature to ask for a password when exiting the application through the task manager, or block it entirely from exiting the application by force? Thanks.
That's just how operating systems work. If an application is killed from the Task Manager, it does not receive any notifications and it cannot refuse to close.
Normally, a workaround for this is revoking user's administrative permissions and running NetWorx under a different user account. In this case the user will not be able to terminate processes of another user.
Alternatively, the system may be configured to disable Task Manager for unprivileged users via the Group Policy Editor (Remove Task Manager policy).
