Microsoft end of support is happening for a broad set of products today, October 14, 2025, including Windows 10 (all editions), Office 2016/2019, Exchange Server 2016/2019, Skype for Business Server 2015/2019, Visio 2016/2019, Project 2016/2019, Visual Studio 2015, Team Foundation Server, and Windows 10 Team for Surface Hub.
This guide outlines what’s ending, risks of staying put, and step‑by‑step upgrade and migration paths that preserve security and compatibility.
What’s ending on Oct 14, 2025
-
Windows 10 Enterprise, Education, Home, Pro, IoT Enterprise, Enterprise LTSB 2015, and Windows 10 Team (Surface Hub) reach end of support on this date.
-
Office 2016 and Office 2019 (including apps like Word, Excel, Outlook, Project, and Visio) reach end of support on this date.
-
Exchange Server 2016 and Exchange Server 2019 reach end of support on this date.
-
Skype for Business Server 2015 and 2019, Visio 2016/2019, Project 2016/2019, Visual Studio 2015, and Team Foundation Server are also ending support.
Why this matters
End of support means no security updates, bug fixes, or technical support, increasing exposure to vulnerabilities and compliance risks. Unsupported systems can continue running but won’t receive quality updates or new features, and many connected services will phase out compatibility. Planning upgrades or migrations now avoids last‑minute downtime and ensures continuity with supported platforms.
Windows 10: paths forward
Windows 10 version 22H2 is the final release of Windows 10, and all editions end support on October 14, 2025. Eligible devices should upgrade to Windows 11 to restore full support and ongoing security updates.
Devices that must remain on Windows 10 can enroll in Extended Security Updates (ESU), a paid program delivering critical and important security updates for up to three years after EOS.
-
ESU basics: enrollment is per device, covers only security updates, and requires Windows 10 version 22H2.
-
Availability and term: ESU can be purchased annually for up to three years post‑support; Year One begins after EOS and licenses are cumulative by year.
-
Cost signals and cloud: Microsoft documents Year One commercial pricing and includes scenarios where ESU is covered with certain cloud subscriptions like Windows 365 and Azure Virtual Desktop.
Office 2016/2019: upgrade choices
Office 2016 and Office 2019 end support on October 14, 2025, with no extended security updates available. Microsoft recommends moving to Microsoft 365 Apps (subscription) or Office LTSC 2024 for fixed environments that cannot adopt a subscription model. Office 2021/2024 may continue to run on Windows 10, but Windows 10 itself is unsupported after EOS, which can affect supportability and security posture.
Microsoft 365 Apps delivers continuous security and feature updates aligned to supported Windows versions. Office LTSC 2024 is designed for regulated or offline scenarios and remains supported on currently supported Windows versions.
Exchange Server 2016/2019: migration plan
Exchange Server 2016 and 2019 reach end of support on October 14, 2025, ending security updates and supportability. Organizations can migrate to Exchange Online for cloud‑hosted email or adopt the supported on‑premises path defined in Microsoft’s Exchange roadmap.
For most organizations, a staged migration to Exchange Online reduces risk and restores a supported posture fastest.
-
Inventory current CUs, schema, hybrid connectors, and third‑party integrations to plan a clean migration sequence.
-
Align mailbox moves, transport rules, and authentication changes with a carefully scheduled cutover or hybrid coexistence period.
Skype for Business Server 2015/2019
Skype for Business Server 2015 and 2019 exit support on October 14, 2025. Microsoft’s recommended path is to migrate to Microsoft Teams for meetings, chat, and calling with modern security and compliance. Plan identity, voice, and meeting interop, then phase users into Teams workloads to minimize disruption.
Visio 2016/2019 and Project 2016/2019
Visio 2016/2019 and Project 2016/2019 hit end of support on October 14, 2025. Migrate to Visio Plan (e.g., Visio Plan 2) and Project subscription offerings or supported LTSC where applicable. Subscription plans deliver ongoing security and feature updates aligned to supported Windows versions.
Visual Studio 2015 and TFS
Visual Studio 2015 exits support on October 14, 2025, ending security fixes for the IDE and associated components. Upgrade to Visual Studio 2022 to regain a supported development toolchain, including modern .NET support and integrated Git. For TFS (Team Foundation Server), follow Microsoft’s upgrade guidance toward Azure DevOps Server or Azure DevOps Services.
Surface Hub on Windows 10 Team
Windows 10 Team (Surface Hub) reaches end of support on October 14, 2025. Migrate Surface Hub 2S devices to Microsoft Teams Rooms on Windows or to supported Windows 10/11 Pro or Enterprise per Microsoft guidance. Validate peripherals, management profiles, and meeting room standards during migration to avoid meeting interruptions.
Risks of staying unsupported
After Microsoft end of support, products stop receiving security updates, increasing exposure to malware, ransomware, and targeted exploits. Unsupported systems can fall out of compliance frameworks that expect current security patches, impacting audits and insurance. Dependencies on unsupported Windows 10 can also affect Office, developer tooling, and device management supportability.
Action checklist
-
Inventory: capture all instances of Windows 10, Office 2016/2019, Exchange 2016/2019, Skype for Business Server, Visio/Project 2016/2019, Visual Studio 2015, TFS, and Surface Hub.
-
Prioritize: schedule upgrades to Windows 11 and Microsoft 365 Apps first, then plan server migrations for mail and communications.
-
Bridge gaps: where upgrades can’t complete by the deadline, enroll eligible Windows 10 devices in ESU to maintain security updates.
Quick answers
-
Can Windows 10 get security updates after EOS? Yes—via the paid ESU program for up to three years, limited to critical/important security updates.
-
Will Office 2016/2019 receive ESU? No—there is no ESU for Office 2016 or Office 2019; applications continue to run but are unsupported.
-
Which Windows 10 version is required for ESU? Devices must be on Windows 10 version 22H2 to receive ESU updates.
As Windows 10, Office 2016/2019, Exchange Server 2016/2019, Skype for Business Server, Visual Studio 2015, and other legacy products reach Microsoft end of support on October 14, 2025, the safest path forward is to prioritize upgrades, migrations, and security hardening so your environment remains supported and compliant.
If certain PCs must remain on Windows 10 beyond this date, enroll eligible devices in Extended Security Updates to receive critical and important security patches while you complete phased hardware refreshes and Windows 11 deployments after Microsoft end of support.
