Mon pc plante a chaque demarrage et redemarre en boucle avec les toutes dernieres mise a jour de windows.
J'ai du mettre l'ordi a un point de restauration anterieur et la dans la barre des taches ya encore ce bouclier jaune qui m'indique que des mise a jour sont pretes.Que dois je faire ?

Aidez moi SVP
