Voila un petit script .bat qui, une fois configuré, vous permetra de définir rapidement (après chaques nouvelle installation par exemple) le comportement de chaques services windows
je ne sais pas si vous voyez l'interet ?
(moi j'ai un double boot avec un windows dédié à la M.A.O. pour lequel je désactive une tonne de services inutiles, je gagne du temps quand je réinstalle xp)
à la place de dislabled on choisira auto ou demand ...

j'ai trouvé la liste des noms de services sur ce site
http://www.theeldergeek.com/services_guide.htm
voila ... tous les avis/ajouts/signalement d'erreurs sont les bienvenus

@echo off
@echo -------------------------------------------
@echo Ce script va desactiver un certain nombre
@echo de services au demarage de windows XP
