What happenedMicrosoft says Windows Server 2016 reaches end of support in January 2027, and the January 2027 update will be its last.
Who is affectedBusinesses and IT teams running any edition of Windows Server 2016: Datacenter, Essentials, MultiPoint Premium and Standard.
What to do
  1. 1Find out whether any of your servers run Windows Server 2016.
  2. 2Ask your IT provider for an upgrade plan to Windows Server 2025.
  3. 3Test Windows Server 2025 first using Microsoft's free 180-day trial.
  4. 4Finish the move before January 12 so security updates do not stop.

Microsoft says Windows Server 2016 will stop getting security updates in January 2027. The January 2027 update will be the last one. Extended support ends on January 12, about three months from now. Any business that still runs this server software has a short window to move.

What changed

Windows Server is the version of Windows that runs behind the scenes in many offices. It can handle shared files, user accounts and company apps. Version 2016 came out in September 2016 and reached general availability on October 12, 2016. Mainstream support ended in January 2022. Extended support is the final stretch, and it is now close to its end.

Microsoft put it plainly: after the last update, devices running Windows Server 2016 will no longer get monthly security updates with protections against the latest threats. That applies to every edition: Datacenter, Essentials, MultiPoint Premium and Standard.

Why it matters

A server that stops getting security fixes keeps working, but it does not get protection against newly found weaknesses. Servers often hold company files and customer records, and many sit at the center of how an office runs. Running one without fixes is a risk that grows over time.

Essentials users face a second change. On the same date, Microsoft will stop supporting all Windows Server 2016 Essentials features, including Remote Web Access and other Essentials-specific functions.

Who it affects

The news is aimed at businesses and IT teams that run Windows Server 2016. If you only use regular Windows computers at home or work, this notice is not about your machines. Anyone already on a newer server release is not covered by this deadline either. If you are not sure what your company runs, ask whoever manages your IT.

What to do

Microsoft advises moving to Windows Server 2025. It reached general availability in November 2024. Microsoft lists mainstream support for it until November 2029 and extended support until November 14, 2034. The steps in the alert box above cover the practical order of work, including a free way to test first.

What happens next

The January 2027 update is the final one, so the deadline will not move on its own. Microsoft's notice, as reported, does not mention any extension. Dates for other Windows versions are on the Windows Lifecycle FAQ page and the Lifecycle Policy search tool. Microsoft also said earlier this month that Windows 11 24H2 Home and Pro stopped getting security updates, a reminder to check other products too.

The takeaway

If any of your servers run Windows Server 2016, start planning the move to Windows Server 2025 now, before January 12.
