Windows 11 26H2 has been available to all users since September 29, 2026. Microsoft has deliberately chosen an unspectacular name for the Fall Update: It introduces hardly any new features, but instead provides a quick transition to the current code base. Those who have already installed 24H2 or 25H2 will hardly notice the update, but they still need to keep one date in mind: Support for 24H2 ends as early as October 13, 2026.
Key Points at a Glance
- Windows 11 26H2 (also known as the “2026 Update”) has been rolling out worldwide since September 29, 2026.
- Technically, it’s a small enablement package, not a major reinstallation.
- There are no new hardware requirements and, so far, no known compatibility issues.
- 24H2 users should upgrade soon, as support ends on October 13, 2026.
- The installation takes only a few minutes and requires only a restart.
What’s the technical background behind Windows 11 26H2?
26H2 shares the so-called servicing branch with its predecessor versions, 24H2 and 25H2. As a result, the update is not delivered as a complete operating system image, but as an enablement package: a small file between 174 KB and 200 KB that essentially just updates the version number and unlocks existing components. Microsoft had already delivered most of the features that are now officially part of 26H2 via the monthly cumulative updates over the past twelve months. So anyone who has been updating their system regularly has long been running most of the technology that 26H2 is now officially introducing.
There is one exception for participants in the Insider Program: Anyone already using the internal preview version 26H1 cannot jump directly to 26H2, as this preview is based on a newer platform.
Who is eligible for the update, and what are the requirements?
The system requirements remain unchanged: 4 GB of RAM, 64 GB of storage space, a 1 GHz processor with at least two 64-bit cores, as well as Secure Boot and TPM 2.0. If you’re not sure whether your computer meets these requirements, you can check using Microsoft’s PC Health Check tool.
Microsoft is rolling out 26H2 in waves rather than to all devices at once. If you’re in a hurry, go to Settings > Windows Update, enable the option “Get the latest updates as soon as they’re available,” and manually trigger the update check.
Here’s what’s new in 26H2
Don’t expect any major interface overhauls. Nevertheless, 26H2 includes several improvements that have been introduced via updates over the past few months and are now officially part of the release:
| Area | New Feature |
|---|---|
| Taskbar | Freely positionable (top, bottom, left, right), additional app actions |
| Start menu | More customization options, including the ability to hide your profile picture |
| File Explorer | AI-powered actions, support for additional file formats |
| Task Manager | Detailed display of NPU usage, including memory consumption |
| Security | Administrator protection against privilege escalation, post-quantum cryptography (ML-KEM, ML-DSA), Windows Hello for third-party fingerprint sensors |
| Enterprise | Windows Autopilot device assignment, restore points, policies for removing preinstalled Microsoft apps |
| Miscellaneous | Emoji 17.0, revised touchpad gestures |

How to Install Windows 11 26H2
For most users, Windows Update is all you need:
- Open Settings and go to Windows Update.
- Enable “Get the latest updates as soon as they’re available.”
- Tap “Check for updates.”
- If version 26H2 appears, select “Download and install.”
- Restart when prompted.
If the update isn’t offered automatically yet, the Installation Assistant from Microsoft’s download page can help. For a fresh installation or an upgrade using bootable media, use the ISO file or the Media Creation Tool. On unofficially supported hardware, you can bypass the TPM and Secure Boot checks using the third-party tool Rufus. However, Microsoft strongly advises against this, as it may result in the loss of future updates and support.
Support Periods: Who Needs to Take Action Now?
The update period varies significantly depending on the edition. Home and Pro versions receive 24 months of security updates, while Enterprise and Education editions receive 36 months. For home users, this means that support for 26H2 runs through October 2028, and for enterprise versions through October 2029.
It’s more urgent to check which version is currently installed. Windows 11 24H2 will lose support on October 13, 2026, while version 25H2 will remain supported until October 12, 2027. Anyone currently running 24H2 should therefore plan to upgrade soon, even if the installation itself only takes a few minutes. Some may recall a similar transition period from Windows 10: After the official end of support, Microsoft briefly provided free security updates for users in Europe —a goodwill gesture that no one should count on for Windows 11 24H2.
Conclusion
Windows 11 26H2 is primarily a version update with little risk. Microsoft has already done the actual work through the monthly updates of the past few months; 26H2 simply formalizes this. For most users, the support schedule is more interesting than the few new features: Anyone still on 24H2 should install the update before October 13, 2026; everyone else can take their time and check at their leisure whether their computer meets the system requirements.
