Notes: Annual Channel (Modern Lifecycle Policy). Start and end dates from Microsoft's lifecycle data export (download.microsoft.com, file dated July 10, 2026), which lists "Version 23H2" under Windows Server Annual Channel with an end date of October 24, 2025; the live lifecycle page no longer lists the version. The end date previously shown here (May 12, 2026, from endoflife.date) did not match Microsoft's data.
Source quality: Every date shown is confirmed in the vendor's own content; anything shown as Unknown is not yet confirmed anywhere.
What the end of support means
- After the final end date the software keeps running, but the vendor no longer ships fixes or security patches. Known vulnerabilities stay open, and compliance or cyber-insurance requirements may treat it as unsupported software.
