Win 7, un peu trop d'accès disques après optimisation ?

Bonjour... Donc j'ai un très vieux pc sous windows 7 32bit que mon cousin a "bidouillé" au début de la semaine sans mon accord avec un soft d'optimisation : Mz7Optimizer bon ok, a part quelques changement dans la façon dont il démarre, il a l'air de mieux fonctionner, par contre je trouve que le disque dur fair un peu plus d'accès, c'est peu être juste une impression.... depuis les modifs la led d'accès clignote ne permanence même quand je n'utilise pas le pc depuis longtemps (mon pc est allumé 24/24) alors que je crois me rapeller sans être sur ,qu'au repos total il y a avait zéro activités disque.... vous en pensez quoi ... ? je vous poste la liste de toutes les modifs faites par le logiciel.... (le log du soft après optimisation) d'avance merci pour votre aide Starting Detection Process
