Microsoft plans to discontinue support for multiple Windows and Office versions by 2026-10-13, affecting millions of users worldwide. Users are encouraged to upgrade to ensure continued security updates.
Versions Affected
- Windows 11 SE and Windows 11 24H2 will lose support on 2026-10-13.
- Office 2021 and Office LTSC 2021 will also become unsupported on 2026-10-13.
- Windows 11 23H2 for Enterprise, Education, and IoT Enterprise ends support on 2026-11-10.
Users of these versions should consider upgrading to Windows 11 25H2 or migrating to Office 2024 or Microsoft 365 for enhanced security features.
Implications and Alternatives
Continued use of unsupported versions increases security risks due to unpatched vulnerabilities. Microsoft recommends using Windows 11 25H2 or later and switching to Office 2024 or Microsoft 365. These newer versions provide security updates and additional features.
Windows 11 24H2 previously caused several user issues such as installation failures and performance problems. Windows 11 SE, designed for educational purposes, also faces discontinuation, potentially impacting schools using the system.
Timelines for Transition
- Windows 11 25H2 support is extended until 2027-10-12.
- Office 2024 offers a one-time purchase option, including security updates.
- Microsoft 365 provides continuous feature and security updates via subscription.
Businesses and individual users must prepare to transition to supported platforms to maintain system security and functionality.
