Windows Server 2022 vs 2025
Windows Server 2022 vs 2025: hotpatching, SMB over QUIC, Active Directory updates, Hyper-V improvements, support timeline and licensing.
Server 2025 launched November 2024 with a fresh 10-year support runway through 2034. The headline features are hotpatching (no-reboot security updates), SMB over QUIC for branch offices, Active Directory schema improvements and Hyper-V GPU partitioning.
Licensing is unchanged — still per-core in 16-core minimum packs, still Standard/Datacenter/Essentials. Same CAL model.

Notre recommandation
Stay on 2022 if you're already deployed, your hardware is happy, and you don't need hotpatching or SMB-over-QUIC in branch offices.
Move to 2025 for new deployments, AD schema upgrades, branch office file shares without VPN, and GPU partitioning for VDI.
