Microsoft has announced that more than 15 of its products and software versions are set to reach the end of support in 2026, signaling a major transition for both individual users and businesses. The list includes popular products such as Windows 11, Microsoft Office 2021, Exchange Server, SQL Server, and several enterprise and developer tools. While these products will continue to function after their support period ends, Microsoft has warned that they will no longer receive security updates, bug fixes, technical assistance, or feature enhancements.
The announcement is part of Microsoft’s regular product lifecycle policy, under which software is supported for a fixed number of years before users are encouraged to migrate to newer versions. As technology continues to evolve and cybersecurity threats become more sophisticated, Microsoft says maintaining older software indefinitely is no longer practical. Instead, the company is focusing on delivering continuous updates through newer operating systems, cloud services, and subscription-based software.
For everyday consumers, one of the most significant products affected is Windows 11 version 24H2. Support for the Home and Pro editions of this release will end in October 2026. Users running this version will need to upgrade to a more recent Windows 11 release to continue receiving monthly security updates and system improvements. Enterprise and Education editions generally receive a longer support lifecycle, but organizations will still need to prepare for eventual upgrades.
Another major change affects Microsoft Office 2021, which will also reach the end of support in October 2026. This includes popular applications such as Word, Excel, PowerPoint, Outlook, Access, Publisher, OneNote, Visio, and Project that were purchased as standalone perpetual licenses. Although these applications will continue to open and function after support ends, Microsoft will no longer release security patches or provide technical assistance, increasing the risk of vulnerabilities over time.
Businesses that rely on Microsoft’s server products will also face important deadlines. Exchange Server 2016, widely used for email management, and SQL Server 2016, a popular database platform, are both scheduled to reach the end of support in 2026. Organizations using these systems are encouraged to migrate to newer versions or cloud-based alternatives such as Microsoft 365 and Azure-based services to maintain security and compliance.
In addition to these widely used products, several developer and enterprise solutions are also approaching retirement. Certain editions of Visual Studio, Team Foundation Server, Microsoft Dynamics products, and other legacy management tools are among those scheduled to lose support during the year. While these products may continue to operate, businesses using them could face compatibility issues with newer operating systems and hardware, making upgrades increasingly necessary.
The products affected include:
- Windows 11 Version 24H2 (Home and Pro)
- Microsoft Office 2021
- Office LTSC 2021
- Microsoft Word 2021
- Microsoft Excel 2021
- Microsoft PowerPoint 2021
- Microsoft Outlook 2021
- Microsoft Access 2021
- Microsoft Publisher 2021
- Microsoft OneNote 2021
- Microsoft Visio 2021
- Microsoft Project 2021
- Exchange Server 2016
- SQL Server 2016
- Several legacy Visual Studio, Dynamics, and enterprise management products
The end of support does not mean that software immediately stops working. Users will still be able to access documents, run applications, and use their systems as before. However, the absence of future security updates poses a growing concern. As cybercriminals continue to discover new vulnerabilities, unsupported software becomes increasingly susceptible to attacks because newly identified security flaws are no longer patched by Microsoft.
For businesses, continuing to use unsupported software can also create regulatory and compliance challenges. Many industries require organizations to maintain supported software as part of cybersecurity standards and data protection regulations. Failure to do so may increase operational risks, expose sensitive customer information, and lead to additional compliance costs.
Microsoft has advised users to check which versions of Windows and Office they are currently running. On Windows devices, users can identify their operating system version through the system settings or by using the “winver” command. Office users can check their version through the Account section within any Office application. Identifying software versions early allows users and organizations to plan upgrades before support officially ends.
The company has increasingly shifted its focus toward subscription-based services such as Microsoft 365, where applications receive regular feature updates and security improvements without requiring users to purchase entirely new versions every few years. This approach allows Microsoft to respond more quickly to emerging security threats while ensuring customers always have access to the latest capabilities.
For enterprise customers, migration planning is particularly important. Upgrading large IT environments often requires testing applications, verifying compatibility with existing infrastructure, training employees, and scheduling deployments to minimize disruption. Organizations that delay these preparations may find themselves facing increased costs and operational challenges as support deadlines approach.
Consumers who use Microsoft 365 subscriptions are less likely to be affected because the service updates automatically with the latest supported versions. However, individuals using standalone Office 2021 licenses or older Windows releases should begin considering their upgrade options well before the deadlines. Purchasing newer versions or transitioning to Microsoft 365 can help ensure continued access to security updates, new features, and technical support.
Microsoft’s latest support schedule reflects the company’s broader strategy of modernizing its software ecosystem while encouraging users to adopt newer technologies designed to meet evolving security and productivity needs. As cyber threats become more sophisticated and digital workplaces continue to expand, staying on supported software is becoming increasingly important for protecting personal data, maintaining business continuity, and ensuring compatibility with the latest hardware and applications.
With more than 15 Microsoft products reaching the end of support in 2026, both individuals and organizations should take the opportunity to review their systems, identify affected software, and plan upgrades accordingly. Acting before the deadlines arrive will help users avoid unnecessary security risks, maintain reliable performance, and continue benefiting from Microsoft’s latest innovations and ongoing technical support.
