Plein de MAJ au démarrage et ordi trés lent !

Bonjour,

Voila mon ordi et moi (!!) on a déménagé au Sénégal il y a 02 mois !! Il n'est pas tropicalisé mais il tient le choc ! Le problème c'est que depuis 15 jours , il est super lent !!!! De plus, en moins de 08 jours, j'ai du avoir au moins 12 mises a jour windows !J'ai fait les trucs de base : cc cleaner , malawarebytes en mode sans échec (rien a signaler !!) ..... je me permet de poster un hijack (j'essaye de comprendre comment les analyser mais pour l'instant je suis pas au point alors je préfère les avis d'expert !!) encore merci !
Voici le rapport :
