Vista, mises à jours impossibles

Bonjour,

Je viens de me débarrasser de Vista Antispyware 2010, et après un état des lieux avec Secunia, il m'indique des failles de sécurités dans certains logiciels. J'ai pu quasiment toutes les corriger, sauf celles de Microsoft (IE7, IE7(64bit), Visionneuse Powerpoint et presque une vingtaine de mises à jour Vista), qu'il refuse de télécharger, il cherche indéfinement. Je me demande s'il n'y a pas des "restes" qui posent problème en bloquant l'accès aux mises à jour Microsoft...

J'ai installé RSIT, fait un log et jeté un oeil, et certaines choses me paraissent suspectes, mais je n'ai pas les connaissances suffisantes pour pouvoir vraiment déterminer les problèmes effectifs.

Est-ce que quelqu'un pourrait jeter un petit coup d'oeil et me dire ce qu'il en pense ?
Merci d'avance.

Voici le log de RSIT :
