Como desactivar la funci鏮 XP SP2 DEP (Prevenci鏮 de ejecuci鏮 de datos).



Editar el fichero boot.ini que esten C:\ y cambiar "/NoExecute=xxxxx" a "/NoExecute=AlwaysOff" et voil..

Como siempre, mejor hacer primero una copia del fichero boot.ini.
Por si las moscas.

Este cambio me ha ido muy bien.


- Pienso incluso que va mejor el SP2 con DEP deshabilitado que el SP1...



boot.ini explanation:

/noexecute
The /noexecute parameter enables Data Execution Prevention (DEP), a set of hardware and software technologies designed to prevent code from running in protected memory locations

/noexecute={alwayson | optout | optin | alwaysoff}

Subparameter

alwayson
Enables DEP for the operating system and all processes.

optout
Enables DEP for the operating system and all processes, administrators can disable DEP on selected executable files by using System in Control Panel.

optin
Enables DEP only for operating system components (Windows).

alwaysoff
Disables DEP. This parameter also disables physical address extension (PAE).

Comments

DEP (and the /noexecute parameter) are supported on Microsoft Windows XP with Service Pack 2 (SP2), Microsoft Windows 2003 with Service Pack 1 (SP1), and later versions of Windows.

The /noexecute parameter is effective only on 32-bit processes. It enables software-enforced DEP and, if the processor supports hardware-enforced DEP, it also enables it. On 64-bit processes, DEP is enabled by default and cannot be disabled (equivalent to /noexecute=alwayson). For these processes, the /noexecute parameter is ignored.

When DEP is enabled on a computer with a processor that supports hardware-enforced DEP, Windows 32-bit version automatically enables physical address extension (PAE). When DEP is disabled, Windows automatically disables PAE.
