Windows Server 2022 mainstream support ends Oct 13
Microsoft's Windows Server 2022 leaves mainstream support October 13, 2026 — but extended support runs five more years with security updates at no extra cost.
airgap Confirmed by Microsoft: Windows Server 2022 leaves mainstream support on October 13, 2026 — 88 days from this writing. Extended support runs five years past that, to October 14, 2031. Security updates continue on the extended channel at no additional cost. Confidence on the dates: high, as stated by Microsoft’s lifecycle policy and covered by BleepingComputer today.
Read for server operators: not a cliff. October’s Patch Tuesday will be the last mainstream release, and every month through October 2031 will keep shipping security fixes on the extended-support channel, same delivery pipe, no ESU purchase. Contrast with Windows 11 24H2 Home and Pro, which reaches the same October 13 date and has no consumer ESU behind it — a real cliff, covered here yesterday.
What stops on October 13
Feature updates for Windows Server 2022 stop. Non-security fixes stop. No-charge incident support and design-change requests wind down with mainstream. The monthly security-update stream keeps flowing.
For most fleets this is a paperwork event, not an incident. What ends is the mainstream product-support channel; what continues is the security-update channel. A 2022 host that takes the October 2026 Patch Tuesday and every one after it through 2031 is not running unpatched code.
Microsoft’s pointer
Migration target is Windows Server 2025, GA since November 2024. Per the lifecycle page, 2025’s mainstream cutoff is November 13, 2029 and extended runs to November 14, 2034 — a three-year forward window from the 2022 mainstream end. A 180-day evaluation build is available for lab testing before commitment.
Timeline
- 2026-10-13 — Windows Server 2022 mainstream ends. Final mainstream Patch Tuesday.
- 2026-11-10 — First extended-support Patch Tuesday for 2022. Security updates only.
- 2029-11-13 — Windows Server 2025 mainstream ends.
- 2031-10-14 — Windows Server 2022 extended support ends. Patch stream stops.
Confidence on the timeline: high, sourced to Microsoft’s lifecycle policy. Confidence on any paid ESU tier for Server 2022 continuing past October 2031: not disclosed as of this writing — treat accordingly. Windows 10’s paid ESU exists as a template; whether Microsoft offers the same for 2022 in 2031 is a decision that has not been made public.
What this does not change
Nothing about July’s exploited zero-days. Nothing about the Fortinet FortiSandbox KEV additions that federal agencies are patching by Sunday. Nothing about the SharePoint deserialization RCE added to KEV yesterday. Windows Server 2022 will receive the fixes for those in October, November, and every month after. The lifecycle change is a planning input for a fleet’s rebuild schedule, not a Patch Tuesday event.
For anyone still running Server 2019 or older: mainstream ended on 2019 in January 2024, extended runs to January 2029. Those hosts are already on the extended channel and the calendar for them has not moved.
