hi all,
there is problem when we disable task manager from registry (like above).
that it only disable the task manager for administrator type of users. the standard type of user's can still access the task manager.

Hi

We can do this with just edit the registry by code

Here my code

    private static void EnableTaskManager(bool enable)

    {

        Microsoft.Win32.RegistryKey HKCU = Microsoft.Win32.Registry.CurrentUser;

        Microsoft.Win32.RegistryKey key = HKCU.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Policies\System");

       key.SetValue("DisableTaskMgr", enable ? 0 : 1, Microsoft.Win32.RegistryValueKind.DWord);

 }


Thank you

I need a solution for all versions of Windows Vista.

Hi,
 
If you need to to do it programmatically, you just need to write a batch file for this action.
 

I'm not looking for the manual way to disable it. I'm looking for the way to disable it through programming. Thanks.

Hi,
If you are using Windows XP, VISTA Business, Ultimate, and Enterprise editions then you can disable the Task Manager through the Local Group Policy Edtitor as well.
Here's how:
1. Click Start
2. Click Run
3. Enter gpedit.msc in the Open box and click OK
4. In the Group Policy settings window
5. Select User Configuration and Select Administrative Templates
6. Select System and Select Ctrl+Alt+Delete options
7. Select Remove Task Manager, Double-click the Remove Task Manager option
8. Click on Enabled radio button and apply the changes.
9. It will disable your task manager.
If you are using any other version of VISTA that is not mentioned in above list (like Home) then you have to do it using registry.
