Disabling Task manager using c# in OS Hardened machine
- by srk
I am using the below code to disable the task manager for a kiosk application which works perfectly
public void DisableTaskManager()
{
RegistryKey regkey;
string keyValueInt = "1";
string subKey = "Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System";
try
{
regkey = Registry.CurrentUser.CreateSubKey(subKey);
regkey.SetValue("DisableTaskMgr", keyValueInt);
regkey.Close();
}
catch (Exception ex)
{
MessageBox.Show("DisableTaskManager" + ex.ToString());
}
}
But when i run this in OS hardened machine i get the following error,
DisableTaskManagerSystem.UnauthorizedAccessException:
Access to the registry key 'HKey_Current_User\Software\Mictrosoft\Windows\CurrentVersion\Policies\System' is denied.
at Microsoft.win32.RegistryKey.win32Error(int32 errorcode, String str)
How can i overcome this ? I need to do this for a Kiosk application.
