Get ready for Windows 11 version 26H2

The next annual update for Windows 11 is coming soon and is already available to Windows Insiders! Windows 11, version 26H2 continues our focus on delivering a predictable, low-disruption update experience for organizations and IT professionals.

For devices already running recent versions of Windows 11, this release should be easy to adopt. It builds on the same platform and servicing approach introduced in prior releases, while continuing to improve how updates are delivered, tested, and deployed.

In this post, we'll walk through how to prepare for Windows 11, version 26H2.

A familiar update experience, refined​

Windows 11, version 26H2 uses the same shared servicing model as recent releases available annually in the second half of the calendar year. Supported devices get this feature update as a small enablement package instead of a full OS replacement.

If your organization is already on Windows 11, version 24H2 or 25H2, the update to 26H2 is similar to a regular monthly update in most environments:

• A small, quick installation
• Minimized disruption to users
• No need for full reimaging or complex deployment motions

Note: Devices running Windows 11, version 26H1 won't be able to update to version 26H2. Instead, they'll have a path to update to a future Windows release. This is because Windows 11, version 26H1 is based on a different Windows core than Windows 11, versions 24H2, 25H2, and 26H2. Here's What to know about Windows 11, version 26H1.

This is possible because multiple versions of Windows 11 share a common servicing branch, including:

• The same source code base
• The same security and quality updates
• The same compatibility validation

The difference between versions is simply which features are enabled.


Shared servicing branch progression

Why this matters for IT organizations​

The shared servicing model isn't just a technical detail. It directly impacts how you manage updates across your environment. Compared to full OS upgrades of the past, Windows 11, version 26H2 comes with reduced deployment complexity, improved compatibility confidence, and faster time to value.

Reduced deployment complexity​

Because features are delivered continuously and enabled later, there's no large "upgrade event." This makes planning easier and reduces operational overhead.

Improved compatibility confidence​

Devices moving between versions on the same servicing branch typically benefit from:

• Existing application compatibility validation
• Lower risk of regressions
• Fewer surprises during rollout

Faster time to value​

With smaller updates and faster installations, organizations can move more quickly to the most current release. New features reach you without lengthy deployment cycles.

Support lifecycle considerations​

As with previous annual feature updates, moving to Windows 11, version 26H2 resets the Windows support lifecycle for your devices.

This provides:

• 24 months of support for Home, Pro, Pro EDU, and Pro for Workstations editions
• 36 months of support for Enterprise, Education, IoT Enterprise, and Enterprise Multi-session editions

What does it mean for your servicing strategy? The annual update becomes a key milestone for maintaining a supported and secure environment.

How to prepare for Windows 11, version 26H2​

Already managing Windows 11 in your organization? Preparing for 26H2 should align with your existing update processes.

1. Validate today​

Begin testing with devices running recent versions of Windows 11 to confirm compatibility with your apps, policies, and infrastructure.

If you'd like to get a peak of what's coming and begin previewing version 26H2 on devices now, the update is available through the Windows Insider Program in the Experimental channel. Otherwise, your organization might prefer to wait for the update to become available in Release Preview before doing more extensive testing. At that stage, the experience is closer to final shipping quality. We'll have more information to share when version 26H2 is in Release Preview.

2. Use your existing deployment tools​

Windows 11, version 26H2 will be available through familiar channels, including:

• Windows Autopatch
• Microsoft Intune
• Windows Server Update Services (WSUS)

3. Plan your rollout rings​

Use your standard deployment rings to:

1. Pilot the update with a small group of devices.
2. Expand gradually based on validation results.

4. Stay current​

Windows features are delivered continuously. Stay up to date with monthly updates to help ensure a smoother transition when the feature update becomes available.


Feature delivery over time with enablement moment

Looking ahead and staying informed​

Windows 11, version 26H2 continues the move toward a more predictable and efficient servicing model. This model helps reduce disruption while helping your organization stay secure and up to date. By building on a shared platform and delivering innovation continuously, Windows enables you to focus less on large upgrade projects and more on delivering value to your users.

We'll continue to share updates and guidance as Windows 11, version 26H2 becomes available. In the meantime, test it in the Windows Insider Program's Experimental channel and use the updated plan-prepare-deploy learning path to get ready.
