La prise en charge de Windows 10 Enterprise LTSC 2021 prend fin le 12 janvier 2027, ne laissant aux organisations que quelques mois pour planifier les 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 s\u2019est termin\u00e9 en octobre 2025, tandis que l\u2019\u00e9dition LTSC a continu\u00e9 de 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 seront confront\u00e9s \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 poser des probl\u00e8mes de conformit\u00e9, en particulier pour les organisations qui utilisent ce syst\u00e8me d\u2019exploitation pour des processus m\u00e9tier importants ou qui traitent des informations sensibles.<\/p>\n\n\n\n

Les entreprises qui utilisent des logiciels ou des \u00e9quipements sp\u00e9cialis\u00e9s pourraient \u00eatre confront\u00e9es \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 doivent commencer par v\u00e9rifier la compatibilit\u00e9 des applications, la configuration mat\u00e9rielle requise, les strat\u00e9gies de s\u00e9curit\u00e9 et les processus de d\u00e9ploiement. Une migration d\u2019entreprise compl\u00e8te 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 \u00e0 la configuration requise pour 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 pour les grands parcs d\u2019appareils.<\/p>\n\n\n\n

Les mises \u00e0 jour de s\u00e9curit\u00e9 \u00e9tendues co\u00fbteront 61 $ par appareil<\/h3>\n\n\n\n

Les organisations qui ne pourront pas terminer leur migration avant janvier 2027 auront la possibilit\u00e9 d\u2019acheter des mises \u00e0 jour de s\u00e9curit\u00e9 \u00e9tendues.<\/p>\n\n\n\n

Les licences ESU seront disponibles via les licences en volume \u00e0 partir du 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 remise 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 il n\u2019inclura pas de nouvelles fonctionnalit\u00e9s ni de support technique g\u00e9n\u00e9ral.<\/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 confirmer l\u2019\u00e9dition de Windows utilis\u00e9e par chaque appareil 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 les versions plus r\u00e9centes de Windows \u00e0 mesure que les versions plus anciennes arrivent en fin de support. Certains analystes estiment qu\u2019un march\u00e9 des PC en croissance 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 nouveaux conseils pour contenir les agents d\u2019IA autonomes.<\/p>\n","protected":false},"excerpt":{"rendered":"
