Ce que ESU fournit réellement
ESU ne couvre que les mises à jour de sécurité — de niveau Critique et Important selon la classification Microsoft. Pas de correctifs de bogues, pas de mises à jour de fonctionnalités, pas de demandes de modification de conception, pas de mises à jour de pilotes ou de firmware. Le support technique est également exclu.
Les mises à jour sont distribuées via Windows Update une fois que vous êtes inscrit, et via les canaux WSUS/Intune standard pour les déploiements en entreprise.

Questions fréquentes
- Mon PC Windows 10 continuera-t-il de fonctionner après octobre 2025 sans ESU ?
- Oui — il ne cesse pas de fonctionner. Vous arrêtez simplement de recevoir des correctifs de sécurité. Au fil du temps, les vulnérabilités non corrigées s'accumulent et le risque de sécurité augmente fortement.
- ESU inclut-il les dernières mises à jour du navigateur Edge ?
- Oui. Microsoft Edge reçoit des mises à jour indépendamment de la version de Windows et continue sur Windows 10 22H2 au moins jusqu'en octobre 2028, avec ou sans ESU.
