In tips 050, 070, and 215, I documented desktop and system feature restrictions.

Additional system feature restrictions are available with SP4 by adding REG_DWORD values at:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

1. To disable the Lock Workstation button, Add Value

     DisableLockWorkstation
     0, the default, leaves it enabled.
     1 disables the Lock Workstation button

2. To disable the Change Password button, Add Value

     DisableChangePassword
     0, the default, leaves it enabled.
     1 disables the Change Password button

3. To disable the Task Manager button, Add Value

     DisableTaskMgr
     0, the default, leaves it enabled.
     1 disables the Task Manager button
