Fermeture windows très très longue

Bonjour,

Depuis quelques temps, la fermeture de windows est très très longue (2, à 3 mn voir plus), et plus longtemps je laisse ma session ouverte, plus la fermeture est longue. J'ai fais un scan HJ. Est-ce que quelqu'un peut m'aider à le décrypter ? Voici le rapport Merci d'avance
