La prise en charge de Windows 10 Enterprise LTSC 2021 se termine le 12 janvier 2027, laissant aux organisations seulement quelques mois pour planifier des mises \u00e0 niveau ou acheter une couverture de s\u00e9curit\u00e9 \u00e9tendue.<\/p>\n\n\n\n

Microsoft a averti les entreprises de se pr\u00e9parer \u00e0 la fin du support<\/a> avant l\u2019\u00e9ch\u00e9ance. Le support standard de Windows 10 a pris fin en octobre 2025, mais l\u2019\u00e9dition LTSC a continu\u00e9 \u00e0 recevoir des mises \u00e0 jour dans le cadre de son cycle de vie plus long.<\/p>\n\n\n\n

Les appareils continueront de fonctionner apr\u00e8s le 12 janvier. Cependant, Microsoft cessera de fournir des correctifs de s\u00e9curit\u00e9, des corrections de bogues, des mises \u00e0 jour non li\u00e9es \u00e0 la s\u00e9curit\u00e9 et une assistance technique.<\/p>\n\n\n\n

Les appareils non pris en charge feront face \u00e0 des risques de s\u00e9curit\u00e9 croissants<\/h2>\n\n\n\n

Les ordinateurs ex\u00e9cutant Windows 10 Enterprise LTSC 2021 deviendront plus vuln\u00e9rables aux menaces nouvellement d\u00e9couvertes une fois que Microsoft cessera de publier des mises \u00e0 jour de s\u00e9curit\u00e9.<\/p>\n\n\n\n

L\u2019absence de support officiel pourrait \u00e9galement cr\u00e9er des probl\u00e8mes de conformit\u00e9, en particulier pour les organisations qui utilisent le syst\u00e8me d\u2019exploitation pour des processus m\u00e9tier importants ou traitent des informations sensibles.<\/p>\n\n\n\n

Les entreprises qui d\u00e9pendent de logiciels ou d\u2019\u00e9quipements sp\u00e9cialis\u00e9s pourraient faire face \u00e0 la transition la plus difficile. Ces syst\u00e8mes n\u00e9cessitent souvent des p\u00e9riodes de test plus longues avant que les \u00e9quipes informatiques puissent approuver un nouveau syst\u00e8me d\u2019exploitation.<\/p>\n\n\n\n

Microsoft recommande de passer \u00e0 Windows 11 LTSC<\/h3>\n\n\n\n

Microsoft recommande Windows 11 Enterprise LTSC 2024 comme principal remplacement de Windows 10 Enterprise LTSC 2021.<\/p>\n\n\n\n

Les organisations devraient commencer par v\u00e9rifier la compatibilit\u00e9 des applications, les exigences mat\u00e9rielles, les politiques de s\u00e9curit\u00e9 et les processus de d\u00e9ploiement. Une migration compl\u00e8te en entreprise peut impliquer des programmes pilotes, des d\u00e9ploiements progressifs, la formation du personnel et des mois de tests.<\/p>\n\n\n\n

Les appareils plus anciens qui ne r\u00e9pondent pas aux exigences de Windows 11 pourraient \u00e9galement devoir \u00eatre remplac\u00e9s. Les limitations mat\u00e9rielles pourraient augmenter les co\u00fbts et retarder les projets de migration, en particulier dans les grands parcs d\u2019appareils.<\/p>\n\n\n\n

Les Extended Security Updates co\u00fbteront 61 $ par appareil<\/h3>\n\n\n\n

Les organisations qui ne peuvent pas terminer leur migration avant janvier 2027 auront la possibilit\u00e9 d\u2019acheter des Extended Security Updates.<\/p>\n\n\n\n

Les licences ESU seront disponibles via les licences en volume le 1er septembre 2026. La premi\u00e8re ann\u00e9e co\u00fbtera 61 $ par appareil.<\/p>\n\n\n\n

Les clients utilisant des outils de gestion bas\u00e9s sur le cloud tels que Microsoft Intune ou Windows Autopatch peuvent b\u00e9n\u00e9ficier d\u2019une r\u00e9duction estim\u00e9e \u00e0 25 %. Cela ram\u00e8nerait le co\u00fbt de la premi\u00e8re ann\u00e9e \u00e0 environ 45 $ par appareil.<\/p>\n\n\n\n

Les organisations peuvent souscrire une couverture ESU pour une dur\u00e9e maximale de trois ans. Le programme continuera de fournir des mises \u00e0 jour de s\u00e9curit\u00e9 jusqu\u2019au 8 janvier 2030, mais n\u2019inclura pas de nouvelles fonctionnalit\u00e9s ni d\u2019assistance technique g\u00e9n\u00e9rale.<\/p>\n\n\n\n

Windows 10 IoT Enterprise LTSC a une \u00e9ch\u00e9ance plus tardive<\/h3>\n\n\n\n

Windows 10 IoT Enterprise LTSC 2021 suit un cycle de vie diff\u00e9rent et restera pris en charge jusqu\u2019en janvier 2032.<\/p>\n\n\n\n

Les administrateurs informatiques doivent v\u00e9rifier quelle \u00e9dition de Windows chaque appareil utilise avant de planifier des mises \u00e0 niveau ou d\u2019acheter des licences ESU. Les syst\u00e8mes ex\u00e9cutant l\u2019\u00e9dition IoT ne sont pas concern\u00e9s par l\u2019\u00e9ch\u00e9ance de janvier 2027.<\/p>\n\n\n\n

Microsoft continue d\u2019inciter les entreprises \u00e0 adopter des versions plus r\u00e9centes de Windows \u00e0 mesure que les versions plus anciennes arrivent en fin de support. Certains analystes estiment que le march\u00e9 croissant des PC pourrait renforcer le monopole de Microsoft sur Windows<\/a>.<\/p>\n\n\n\n

L\u2019entreprise a \u00e9galement expliqu\u00e9 pourquoi la modernisation de l\u2019interface de Windows 11 reste lente<\/a> et publi\u00e9 de nouvelles recommandations pour contenir les agents IA autonomes.<\/p>\n","protected":false},"excerpt":{"rendered":"
