Bonjour,
L'explorateur sous Vista "mouline" lamentablement quand je change de répertoire. J'ai supprimé tous les services inutiles (je pense), et malgré un léger mieux, c'est toujors galère : il faut 5 à 10 secondes pour choisir le répertoire où enregistrer un .doc !
JE crois que c'est bien connu avec Vista, mais j'ai du mal à m'y résigner.

Donc, je m'adresse à vous tous, qui pourrrez peut être m'aider.
Je copie ci dessous le rapport HijackThis, en espérant que ça aide. J'ai fait tourner AdAware, CCleaner, et je lance la défragmentation cette nuit...
Merci d'avance si vous m'apportez une solution.
