Bonjour,
j'ai un probleme comparable à certains sur ce meme forum, mais rien n'y fait. j'ai suivi les indications trouvées ici et là mais non. le centre de securite windows m informe que mes mises a jours sont sur off j ai beau remettre sur automatique (j'ai tenté bcp de choses!) l'alerte se réaffiche à chaque demarrage...
je me permets de poster le dernier log de AVC
