nx [Optin |OptOut | AlwaysOn |AlwaysOff]
Optin
Enables
DEP (Data Execution Prevention) only for operating system components, including
the Windows kernel and drivers. Administrators can enable DEP on selected
executable files by using the Application Compatibility Toolkit (ACT).
Optout
Enables
DEP for the operating system and all processes, including the Windows kernel
and drivers. However, administrators can disable DEP on selected executable
files by using System
in Control Panel.
AlwaysOn
Enables
DEP for the operating system and all processes, including the Windows kernel
and drivers. All attempts to disable DEP are ignored.
AlwaysOff
Disables DEP. Attempts
to enable DEP selectively are ignored.
On Windows Vista, this parameter also
disables Physical Address Extension (PAE). This parameter does not disable PAE
on Windows Server 2008.
