    J’ai récupérée mon alienware cet après-midi parce que son disque dur était mort, donc changé tout allait bien, jusqu’a ce que je télécharge Cloudnet via un logiciel pour trouver une clé pour Windows 10 qui n’était pas activé.
    Depuis (19H) je ne peux pas installer MalwaresBytes, ni McAfee, tout Windows est bloqué, j’ai essayer toutes les astuces manuelles possible rien ne fonctionne… j’ai fais une restauration du système et depuis tout et noir, j’ai essayer de redémarrer, rien, toujours noir…
    Je vais laisser tourner le pc cette nuit voir si il se relance un moment …
    Je ne sais pas quoi faire je suis vraiment perdue et j’ai très envie de pleurer…

    Un conseil s’il vous plait ??

    Merci beaucoup :'(

    Bonjour, il apparaît qu’il y a eu des actions sur votre ordinateur, qui ont entraîné la suppression de fichiers de démarrage Windows clés. Ces types de fichiers peuvent être récupérés si vous utilisez le disque d’installation de Windows, mais je vous recommande vivement de démarrer un système d’exploitation en direct avec un dossier Unlocker, qui vous aidera à déverrouiller et récupérer tous vos fichiers sur un lecteur flash ou d’autres méthodes externes.

    Un tel système d’exploitation en direct qui sera en mesure de déverrouiller les fichiers Windows est connu comme “Windows 7 LiveCD [Xemom1]”. Il a la fonction AntiWinLocker qui déverrouille les dossiers de votre disque dur même si vous n’êtes pas connecté à Windows. Après avoir extrait vos fichiers, vous pouvez librement réinstaller Windows :).
