Windows 11 version 26H2 build 26300.9550 now generally available



 Windows IT Pro Blog:

Windows 11, version 26H2 is now generally available, delivering the next annual feature update for Windows 11. Built on the same servicing foundation as Windows 11, versions 25H2 or 24H2, version 26H2 continues Microsoft focus on providing a predictable, low-disruption update experience for organizations while delivering the latest Windows innovations, security improvements, and management enhancements.

Windows 11, version 26H2 is delivered as an enablement package for eligible devices running Windows 11, versions 25H2 or 24H2. This means you can move to the latest release with minimal deployment overhead and a streamlined installation experience.


What is Windows 11, version 26H2?​

Windows 11, version 26H2 is the latest annual feature update for Windows 11 and continues Microsoft annual release cadence for commercial customers.

Like version 25H2, version 26H2 shares the same servicing branch and underlying code base as previous releases. New features and capabilities have been delivered to supported devices through monthly cumulative updates, with some functionality remaining dormant until activated by the version 26H2 enablement package. This approach reduces disruption while simplifying validation and deployment planning.

Why an enablement package?​

Traditional Windows feature updates often required a full operating system upgrade. For eligible devices running Windows 11, versions 25H2 or 24H2, version 26H2 is activated through a lightweight enablement package.

An enablement package:
  • Activates features already present on the device.
  • Installs similarly to a monthly quality update.
  • Requires a small download.
  • Typically results in faster installation times.
  • Allows your organization to use existing servicing and deployment processes.
Because versions 26H2, 25H2, and 24H2 share a common servicing branch, many organizations might find that validating version 26H2 requires less effort than a traditional feature update.

What's new in Windows 11, version 26H2​

Windows 11, version 26H2 bundles features and enhancements gradually rolled out over the last year to versions 25H2 and 24H2 in the areas of security, management, accessibility, and productivity.

Security improvements​

Windows continues to build on Microsoft commitment to security by default and security by design.
  • Administrator protection provides just-in-time administrative privileges and profile separation to help harden Windows against elevation-of-privilege attacks. You can enable it through Microsoft Intune or Group Policy.

  • Built-in Sysmon functionality in Windows enables you to capture system events that security tools can use for threat detection. Sysmon is off by default. You can configure it to capture the events your organization needs.

  • Smart App Control can now be turned on or off without requiring a clean installation of Windows, making it easier to block untrusted or potentially harmful apps.

  • Windows Hello Enhanced Sign-in Security expands support to compatible peripheral fingerprint sensors. As such, enhanced biometric sign-in protection is available on more Windows 11 PCs.

  • Post-quantum cryptography improvements include API support for NIST-standardized ML-KEM and ML-DSA algorithms. They include support for key exchange, signing, and decryption through CNG and .NET.
  • Driver security enhancements change how the Windows kernel trusts third-party drivers. They remove default trust for cross-signed drivers while maintaining support for WHCP and designated trusted legacy drivers.

Management and deployment enhancements​

Windows 11, version 26H2 introduces improvements designed to help IT administrators deploy, manage, and secure devices at scale.
  • Windows Autopilot device preparation supports device association. It helps organizations identify trusted devices before enrollment and enabling device-targeted policies, automatic corporate device enrollment, and additional OOBE customization.
  • Windows settings backup and restore expands first sign-in restore to Microsoft Entra hybrid joined devices, Cloud PCs, and multi-user environments. Use it to restore user settings and Microsoft Store apps during device refreshes, upgrades, and migrations.
  • Point-in-time restore for Windows provides another recovery option. Roll back a PC, including apps, settings, and personal files, to a recent automatic restore point.

  • Policy-based app removal gives organizations more flexibility to remove preinstalled Microsoft apps on Enterprise and Education devices. Just specify additional MSIX and APPX packages through Group Policy.
  • RSAT on Arm64 enables IT administrators to use tools including Server Manager, Group Policy Management Tools, DNS Server Tools, DHCP Server Tools, and Active Directory management tools on Windows 11 Arm64 devices.
  • App update orchestration allows participating applications to coordinate updates with Windows Update for improved scheduling and a more streamlined update experience

User experience and accessibility enhancements​

Windows 11, version 26H2 continues to improve everyday productivity with enhancements across Windows experiences.
  • File Explorer adds productivity enhancements including AI actions for working with supported images and summarizing OneDrive and SharePoint documents. Also included are quick actions for work and school accounts, support for additional archive formats, and performance improvements.

  • Windows Search makes results easier to find and understand with previews. It better handles typos and partial app names, identifies result types clearer, and automatically indexes frequently used folders.
  • Start and taskbar enhancements provide additional ways to customize the Windows workspace. Begin with new Start menu views and sizing options, additional taskbar positions, and a smaller taskbar option.

  • Task Manager provides greater visibility into NPU usage, including NPU utilization and memory information. You can also identify applications running in an AppContainer.

  • Magnifier adds clearer screen reader announcements, more precise zoom controls, and screen tint options to improve readability.

  • Narrator adds Braille Viewer, improves reading and navigation in Microsoft Word, and provides more control over how information about on-screen controls is announced.

  • Voice access adds natural language commanding on supported Copilot+ PCs, additional language support, and Voice Isolation to help improve recognition in environments with other speakers or background noise.

Now enabled by default​

Some features that were behind temporary commercial control in Windows 11, version 25H2 are now enabled by default in version 26H2. These include:
  • Windows settings backup, which helps preserve supported Windows settings and Microsoft Store app lists for recovery and device replacement scenarios. Existing administrator-configured policies are still honored.
  • App-specific taskbar actions that help users access common actions directly from taskbar experiences.
  • File Explorer improvements focused on improving navigation and usability within File Explorer.
Some of these features have eligibility requirements. Please see related technical documentation for more details.

For a closer look at new features and enhancements added to Windows 11 since version 25H2, please see What's new in Windows 11, version 26H2.

Servicing and support lifecycle​

Windows 11, version 26H2 continues Microsoft annual Windows feature update cadence. Installing Windows 11, version 26H2 resets the support lifecycle for supported editions, as noted here:

Edition​
Support duration​
Home24 months
Pro24 months
Enterprise36 months
Education36 months

Deployment considerations​

For devices currently running Windows 11, version 25H2 or version 24H2, you can use existing deployment frameworks and update rings to validate and deploy version 26H2.

As with any release, we recommend that you:
  • Validate version 26H2 in pilot environments.
  • Test business-critical applications, representative hardware, and workflows.
  • Expand deployment through existing update rings.
  • Monitor deployment health and known issues.
It is also a good time to review security and compliance requirements and educate support personnel on any new functionality.

Because this release uses servicing technology like that used for monthly cumulative updates, many organizations should experience a streamlined deployment process.

Tools and resources​

Deployment, security, and management tools have been refreshed for this update. These include:
We've also updated key references and documentation:
Monthly release notes for Windows 11, version 26H2 will be added to the update history page beginning with the first monthly security update for version 26H2, slated for October 13, 2026.

Start planning for Windows 11, version 26H2​

Windows 11, version 26H2 is designed to make moving to the latest version of Windows familiar and straightforward. If you're managing eligible devices on Windows 11, version 25H2 or 24H2, start by validating the update with a targeted set of devices, applications, and workflows. Then expand your deployment using the tools and processes you already have in place.

As always, we want to hear from you. Drop a comment below and let us know what's working, what questions you have, and what we can do to make managing Windows easier for your organization.

File History is working after KB512010.
26H2 is an enablement package for features, not bug fixing.
This is true but one would think that a final release would be free of existing bugs...Not in Redmond.

That's true. Microsoft is the only software company in the world that ships products with bugs in it. No other software company in history has done that.

Yes, I see the sarcasm, but... Microsoft is much better at shipping software with bugs in it, than anyone else. ^^

They should just name their next OS something like... Windows Cockroach. :D

It is not the only one, but most other SW companies do not have a Feedback Hub that has many reports of bugs but either ignores them or waits for Patch Tuesday, for minor bugs that is OK.

That's true. Microsoft is the only software company in the world that ships products with bugs in it. No other software company in history has done that.
No software is provably bug free but software from competent firms has fewer bugs and better software QA. Microsoft is not in this category.

I think he meant... KB5124010
I don't see any KB51201xx on my update history.
I have that update which fixes FH linking to the right drive. However, when run it doesn't copy new files!

I made a Macrium backup first. I just don't trust MS updates anymore. It's a small amount of time for the extra insurance and peace of mind.

Any ideas on why - after (manually) installing the enablement package to an (up to date) 25H2 VM - I do not see any of the new features?

The OS UI is completely devoid of any of the new stuff and is identical to the prior 25H2?

Example: Start menu - should be something like this:

1790776451898.webp

But I see this:

You need to wait. Not all the new features coming immediately after update.

I guess I am not understanding what you are saying.

According to every source I have read out there - all these "features" have been piling up on mine (and everyone elses) machine - in a dormant state for months now.

All we need is the "key" (KB5121794) to unlock these features and away we go.

While I do understand that MS will be doing a controlled rollout for the "key" itself - I have read NOTHING to indicate that any of the "new" features have any way of "still arriving" to machines out there.

If one has kept a 25H2 install - 100% up to date - all the 26H2 features are already there.

KB5121794 should unlock them for anyone who wants them - like today.

You would think, but no, it’s still controlled rollout. New features seemingly come every month, and a lot of them are backported to 24H2 and 25H2 devices.

I’m not even sure what a “feature update” means anymore.

After installing 26H2 this morning on my Lenovo T490, I tested 3 boot USB drives I have to see if they still work.

1. Windows recovery drive still boots fine.
2. Macrium X rescue drive still boots fine.
3. Rufus 4.15 boot drive with Mosby 3.4 which I just created yesterday under 25H2 no longer boots. I found out that the Rufus drive will boot if I disable Secure Boot in the BIOS/UEFI.

Wow - OK. I stand corrected. And yes - I also do not understand what a feature update means anymore either.

Question: Would a new 26H2 ISO contain the full feature set right out of the box? Or is that still going to have stuff seeded to it for months and months?

    UPDATE - 11 April 2026: due to lid hinges starting to break up this laptop has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

    I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.

    Info for 2021-2026:
    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.
