Cela signifie que les appareils compatibles peuvent recevoir cette version via un petit package d\u2019activation, et que la nouvelle mise \u00e0 jour pourrait occuper moins de 200&nbsp;Ko. L\u2019entreprise d\u00e9crit le processus comme similaire \u00e0 l\u2019installation d\u2019une mise \u00e0 jour mensuelle. Les utilisateurs devraient constater des installations plus rapides, moins de perturbations et l\u2019absence de n\u00e9cessit\u00e9 de reconstruire l\u2019image syst\u00e8me compl\u00e8te.<\/p>\n\n\n\n<p>Cette approche fonctionne car les versions 24H2, 25H2 et 26H2 partagent la m\u00eame base de code source. Elles partagent \u00e9galement les mises \u00e0 jour de s\u00e9curit\u00e9, les correctifs de qualit\u00e9 et la validation de compatibilit\u00e9. La diff\u00e9rence de fonctionnalit\u00e9s provient des capacit\u00e9s qui sont activ\u00e9es. Microsoft indique que les probl\u00e8mes affectant 26H2 devraient \u00e9galement affecter 25H2 dans ce mod\u00e8le partag\u00e9.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-26h1-users-face-a-completely-different-upgrade-path\">Les utilisateurs de 26H1 sont confront\u00e9s \u00e0 une voie de mise \u00e0 niveau compl\u00e8tement diff\u00e9rente<\/h3>\n\n\n\n<p>Il y a une r\u00e9serve de taille pour les utilisateurs de Windows 11 26H1. Microsoft indique que ces appareils ne peuvent pas \u00eatre mis \u00e0 niveau directement vers 26H2, car 26H1 utilise un c\u0153ur Windows diff\u00e9rent. Pour les organisations, Microsoft recommande de tester 26H2 via le Programme Windows Insider. Les outils existants, notamment Intune, Autopatch et WSUS, prendront en charge le d\u00e9ploiement.<\/p>\n\n\n\n<p>La mise \u00e0 jour r\u00e9initialise \u00e9galement le cycle de vie du support. Les \u00e9ditions Famille et Professionnel b\u00e9n\u00e9ficient de 24 mois de support, tandis que les \u00e9ditions Entreprise et \u00c9ducation b\u00e9n\u00e9ficient de 36 mois de support.<\/p>\n\n\n\n<p>Microsoft n\u2019a pas encore communiqu\u00e9 de date de sortie publique d\u00e9finitive. Toutefois, l\u2019entreprise indique que 26H2 est d\u00e9j\u00e0 disponible via le canal exp\u00e9rimental Insider, et que des tests plus larges sont pr\u00e9vus ult\u00e9rieurement.<\/p>\n\n\n\n<p>En ce qui concerne les prochaines fonctionnalit\u00e9s, le nouveau build exp\u00e9rimental de Windows 11 26H1 a \u00e9t\u00e9 publi\u00e9 r\u00e9cemment ; vous pourriez donc avoir envie de l\u2019essayer.
