Most users can now upgrade to Windows 11 26H2, even from Windows 10

A few weeks after the rollout began, Microsoft has announced that all eligible Windows users can now upgrade to the latest OS build on their compatible systems. Despite no major new features, the enhanced security benefits should be enough to entice most users. Microsoft recently clarified its instructions for installing the most recent version of Windows 11.

Now, Windows 11 version 26H2 is available to all eligible devices, including those running 25H2 and 24H2 releases, as well as most modern PCs. The upgrade process also supports the latest Windows 10 version enrolled in Microsoft's extended support program. While Windows 10 reached its scheduled end of life in 2025, Microsoft has repeatedly extended the period for customers who wish to continue using it.

Now, Windows 10 home users can receive free, officially sanctioned security updates until October 2027. After that, the system should remain secure with the 0patch micropatching solution for many years. Microsoft has confirmed that current Windows 10 builds can still receive the latest OS edition for free, following initial extensions to earlier Windows 10 versions, which are no longer available.

Both Windows 11 and 10 share a common licensing structure, which should facilitate the installation of the newest OS build in various scenarios. Many people may still prefer Windows 10 to avoid potential changes in Windows 11, although enterprise organizations may consider the free upgrade option to transition away from the platform they have relied on for years.

Windows 11 26H2 was released on September 29, 2026, for both x86-64 and Arm CPU architectures. Microsoft described this update as predictable and with minimal disruption, offering increased stability and compatibility compared to previous versions. Essentially, Windows 11 26H2 merely activates dormant features that were already present in earlier releases.

Microsoft has been striving to enhance the performance and reliability of Windows 11. However, AI-assisted vulnerability discovery has revolutionized software security, compelling the company to release extensive bug-fix packages that address thousands of security flaws detected by both Microsoft's AI and third-party researchers.
