Overview
- Microsoft will stop support for SQL Server 2016, SharePoint Server 2016 and 2019, and Project Server 2016 and 2019 on July 14, 2026, which ends security updates for those server products.
- A larger wave of end‑of‑support takes effect on October 13, 2026, when Windows 11 24H2 Home and Pro, Office 2021 (including LTSC builds), Windows Server 2012/2012 R2 ESUs and Windows 11 SE will no longer receive updates or fixes.
- Microsoft will remove Microsoft Publisher from Microsoft 365 after the October cutoff so subscribers will no longer be able to open or edit .pub files in the cloud while locally installed Publisher apps will keep working.
- Affected users can upgrade to Windows 11 25H2 (which Microsoft will update through October 12, 2027), buy Office 2024 at full price, or move to Microsoft 365 subscriptions, each option carrying costs, testing and admin work.
- The cutoffs raise practical risks for schools, businesses and home users because millions still run the affected versions, Extended Security Updates are expiring for some servers, and past rollout problems with 24H2 increase migration caution.
