Espace disque insuffisant sur XP pack2

Bonjour,
je recherche de l'aide pour optimiser le démarrage de mon ordinateur et pour résoudre un problème d'espace sur C:\
Mon disque dur est partitionné entre C:\ (windows, programmes files) de 10Go, et D:\ (données personnelles).

Comme défini dans un autre message de ce site, j'ai nettoyé avec CCleaner
j'ai effectué les scans avec AVG Spyware, Bitdefender (scan online) et Hijackthis

je joins les rapports.
merci de me dire si mon PC peut etre amélioré car j'ai des pubs intempestives.
