Assuming you meant Windows Server 2022 Version 21H2 (OS Build 20348.587) — here’s a structured review based on real-world server administration feedback.
Released in August 2021, Windows Server 2022 is the Long-Term Servicing Channel (LTSC) release built on the same underlying code as Windows 10 version 21H2 and early Windows 11. However, it is not a client OS. It introduces enterprise-focused innovations.

# Check actual build number (not the fake one)
[System.Environment]::OSVersion.Version
# Or
Get-ItemProperty "HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion"
You’ll see 20348.xxxx — not 20348587.20.
From 20348.587, you can upgrade directly to 20348.xxxx (e.g., 20348.1249, 20348.1726) via latest cumulative updates. No need for feature update – Server 2022 v21H2 is the final LTSC build line (no 22H2 or 23H2 for Server 2022).
