A l’occasion du Patch Tuesday de mai 2019 Microsoft publie plusieurs nouvelles mises à jour cumulatives Windows 10. Elles s’attaquent principalement à la sécurité.
La grande maintenance mensuelle de Microsoft vient de débuter. Le service Windows Update propose plusieurs nouvelles mises à jour cumulatives pour Windows 10. Le focus est la sécurité avec des correctifs visant certains composants et logiciels natifs comme les navigateurs Microsoft Edge et Internet Explorer.
Toutes les versions de Windows 10 sont concernées cependant les regards sont tournés vers Windows 10 v1809. Il s’agit de la version stable la plus récente. Microsoft s’apprête cependant à déployer d’ici la fin du mois May 2019 Update. La RTM est actuellement en test au travers du programme Windows Insider.
Pour revenir à Patch Tuesday de mai 2019, il donne naissance à
- KB4494441 pour Windows 10 v1809
- KB4499167 pour Windows 10 v1803
- KB4499179 pour Windows 10 v1709
- KB4499181 pour Windows 10 v1703
Pour le moment, il n’est pas possible d’affirmer que tout se déroule sans problème. Les installations débutent et un peu de temps est nécessaire. Il est conseillé de faire une sauvegarde de son installation Windows si vous souhaitez les installer immédiatement. L’autre solution est de patienter histoire de s’assurer qu’aucun problème n’est à l’ordre du jour.
