Microsoft says Windows 11 version 26H2 is available for eligible 24H2 and 25H2 devices through a phased rollout. Check the official download page and release-health notices before installing.
What Microsoft has confirmed
Microsoft announced the Windows 11 2026 Update, also known as Windows 11 version 26H2, on September 29, 2026. Microsoft says the update is available for eligible devices running Windows 11 versions 24H2 and 25H2, with availability expanding through a controlled rollout.
For eligible devices, 26H2 is delivered as an enablement package. That means much of the underlying release content is already present through servicing updates, and the version change can require a comparatively small download and a restart. Availability is not universal on the same day: a compatibility safeguard can delay the update for a device.
- Use Windows Update first when it offers 26H2 for your eligible PC.
- Do not treat the absence of the update option as proof that Windows is broken.
- Check Microsoft’s release-health information for current known issues and safeguard holds.
Does “26H2 is available” mean every ISO is the right choice?
No. Update availability and installation-media choices are related but not identical. Microsoft’s official Windows 11 download page is the starting point for current public installation media, while the Windows Insider ISO page serves preview builds. Confirm the exact product, language, architecture and intended installation route before downloading.
Do not use an unofficial ISO mirror or a hash copied from a different release. If Microsoft publishes a checksum for the exact image, compare the downloaded file with that value before using it.
Choose the least disruptive path
If Windows Update offers the feature update and the PC is stable, that is usually the simplest route. Use installation media when you have a specific reason, such as a planned clean installation or recovery workflow, and make a verified backup first. A clean install can erase data on the selected disk.
If the PC already freezes, loses its drive, overheats or crashes, investigate those symptoms before attempting a major OS installation. A new Windows version does not repair failing hardware.

Frequently asked questions
Is Windows 11 version 26H2 available now?
Microsoft announced availability on September 29, 2026 for eligible devices running 24H2 and 25H2. The rollout is phased, so not every eligible PC will be offered the update at once.
Should I install 26H2 from an ISO if Windows Update does not offer it?
Not automatically. First check eligibility and Microsoft’s current release-health information. A safeguard hold may be intentional, and forcing an update can create compatibility problems.
Where should I download Windows 11 installation media?
Start with Microsoft’s official Windows 11 download page and follow the option documented for your device and task. Avoid unofficial mirrors.
