Le PC ne s'éteint pas (MAJ en cours)

Bonjour,
Depuis quelques jours, je suis obligé d'éteindre mon ordinateur manuellement, car une MAJ de Windows XP a visiblement du mal à s'installer (avec le message classique 'n'éteignez pas votre ordinateur, il s'éteindra automatiquement...). Qeulqu'un sait-il à quoi cela est dû? A toutes fins utiles, je joins le scan de 'hijackthis'.
Merci d'avance!
