How to Get the Windows 11 2026 Update (26H2)

Windows 11 version 26H2 is available through Windows Update for eligible PCs. To get it, open Settings → Windows Update, select Check for updates, and choose Download & install if the update appears. You can also turn on Get the latest updates as soon as they’re available. Microsoft confirms that the rollout has reached full availability for eligible Windows 11 24H2 and 25H2 devices as of October 21, 2026.

If Windows 11 26H2 is not showing on your PC, the next step is to check your Windows version, pending updates and any compatibility restrictions before trying another installation method.

Check whether your PC can get Windows 11 26H2

Windows 11 26H2 is designed to update eligible PCs running Windows 11 version 24H2 or 25H2 through an enablement package. This is a small update that activates features already delivered through monthly servicing updates, rather than requiring a completely new operating system installation for every eligible device.

Which Windows 11 versions qualify?

First, check which version your PC currently runs.

Current Windows version	What to do
Windows 11 25H2	Check Windows Update for version 26H2.
Windows 11 24H2	Check Windows Update and install the required servicing updates.
Windows 11 23H2 or older	Do not assume the same enablement-package route applies. Check Microsoft’s current upgrade guidance for your device.
Windows 10	Follow Microsoft’s Windows 11 upgrade guidance and confirm that your PC meets the Windows 11 requirements.

The documented enablement-package route applies to Windows 11 24H2 and 25H2. The correct path for other versions depends on the current upgrade requirements and supported installation methods.

How to check your current Windows version

1. Open the Run dialog

Press Windows + R on your keyboard.

2. Enter winver

Type winver and press Enter.

3. Read the version information

Note the Windows version and OS build. You can use these details to determine which installation path applies to your PC.

Prepare your PC before installing

Before you begin, take a few minutes to prepare:

• Save your work and back up important files.
• Connect your laptop to power.
• Make sure you have enough free storage for the update.
• Install any pending Windows updates and restart if prompted.
• Check for known compatibility issues on Microsoft’s Windows 11 26H2 release-health page.

Important: The September 22, 2026 cumulative update KB5124010, or a later cumulative update, is a prerequisite for the documented enablement-package route. Windows Update may manage the required servicing updates for you, so check what your PC offers before attempting a manual installation.

How to install Windows 11 26H2 through Windows Update

For an eligible PC running Windows 11 24H2 or 25H2, Windows Update is the recommended starting point. It handles the update offer through Microsoft’s servicing process and is the simplest route for most home users.

Step 1: Open Windows Update

bitdefender.com

Open Start → Settings → Windows Update. You can also right-click Start, select Settings, and choose Windows Update from the sidebar.

Step 2: Turn on the latest-updates option

windowscentral.com

Find Get the latest updates as soon as they’re available and turn it on if you want to receive eligible updates as soon as Microsoft offers them to your device.

This setting does not override compatibility restrictions or guarantee an immediate offer. Microsoft still controls update availability for devices affected by known issues.

Step 3: Check for the Windows 11 2026 Update

Select Check for updates and allow Windows to look for available updates. If version 26H2 is offered, Windows Update will display the feature update.

If it is not offered, do not assume that Windows Update is broken. Follow the troubleshooting steps later in this guide before attempting a manual upgrade.

Step 4: Select Download & install

When Windows 11 version 26H2 appears, select Download & install. If a See what’s in this update link is available, you can review the update information before proceeding.

Wait for Windows to download and prepare the update. Keep your device connected to power and avoid interrupting the process.

Step 5: Restart your PC

When Windows asks you to restart, save your work and allow the installation to finish. For eligible 24H2 and 25H2 devices using the enablement-package route, Microsoft describes the process as a small update completed with a single restart.

The time required can vary with device performance, update state and other pending maintenance. Do not force the computer to shut down while Windows is applying the update.

What to do if Windows 11 26H2 is not showing

If Windows 11 26H2 does not appear in Settings, check the simplest causes first. Confirm your current version, install pending updates, and review Microsoft’s release-health information before trying a different installation method.

If Windows Update has pending updates

Open Settings → Windows Update and install available updates. Restart if Windows asks you to, then return to Windows Update and select Check for updates again.

The prerequisite for the enablement-package route is a later cumulative update at or beyond KB5124010. Installing current servicing updates through Windows Update is generally safer than manually hunting for an individual prerequisite package.

If the latest-updates option is enabled but 26H2 is missing

Try these steps in order:

1. Confirm that your PC runs Windows 11 version 24H2 or 25H2.
2. Install pending Windows updates and restart.
3. Check your internet connection and make sure your PC has enough free storage.
4. Review the Windows 11 26H2 known issues and notifications page.
5. If the update remains unavailable, wait or use Microsoft’s support guidance rather than forcing an upgrade.

As of October 21, 2026, Microsoft reports that the phased rollout has reached full availability for eligible 24H2 and 25H2 devices. That does not mean every PC must receive the offer: compatibility safeguards and device-specific policies can still affect availability.

If Microsoft has placed a safeguard hold on your device

A safeguard hold prevents Windows Update from offering a feature update to a device that may be affected by a known compatibility problem. Microsoft uses these holds to reduce the risk of failed upgrades, rollbacks, data loss or loss of important functionality.

If Windows indicates that an update is on its way but is not ready for your device:

• Check the official release-health page for the relevant issue.
• Install any available fix when Microsoft recommends it.
• Wait for the safeguard to be lifted before attempting the upgrade.

Do not bypass a safeguard hold simply to install 26H2 sooner. Microsoft explicitly recommends waiting until the issue is resolved and the hold is released.

If your PC is managed by work or school

Your organization may control feature updates through Windows Update policies, Windows Server Update Services (WSUS), Windows Autopatch or other management tools. In that case, the optional-update setting may not determine when the update becomes available.

Contact your IT administrator before attempting a manual installation. Microsoft provides separate deployment guidance for commercial and education customers.

How to download Windows 11 26H2 manually

If you need to reinstall Windows, create installation media or perform a supported upgrade that is not available through the usual Settings workflow, start with Microsoft’s official Download Windows 11 page.

Microsoft currently lists Windows 11 2026 Update, version 26H2, as the current release on that page.

Installation Assistant vs. ISO vs. installation media

Method	Best use	Important limitation
Windows Update	Normal upgrade on an eligible PC	The offer depends on eligibility and compatibility.
Windows 11 Installation Assistant	Supported upgrade on the PC you are using	Microsoft lists support for x64 processors, not Arm-based PCs.
Windows 11 ISO	In-place upgrade or creating installation media	You must select the correct architecture and follow the supported installation process.
Media Creation Tool	Creating bootable installation media	Microsoft’s tool creates x64 media; it cannot create media for Arm-based PCs.

These methods serve different purposes. Microsoft’s Installation Assistant requires administrator access and at least 9 GB of free disk space for its download. The Media Creation Tool requires a blank USB drive with at least 8 GB if you choose that route, and it erases the USB drive’s existing contents.

How to use the Installation Assistant

If you have decided that a manual upgrade is appropriate and your device meets the requirements:

1. Open Microsoft’s Windows 11 download page.
2. Locate Windows 11 Installation Assistant and select Download Now.
3. Run the downloaded tool as an administrator.
4. Follow the compatibility checks and license prompts.
5. Select Accept and Install if the tool confirms that your device can proceed.
6. When prompted, select Restart Now and allow Windows to finish.

Microsoft warns that installation may take some time and that the PC can restart multiple times. Keep it connected to power and do not turn it off during the process.

Important: The Installation Assistant is not a tool for bypassing a Windows 11 26H2 safeguard hold. If Windows Update is withholding the update because of a known compatibility issue, investigate the issue before proceeding.

When to use an ISO or USB drive

An ISO or bootable USB is more useful when you need installation media, are reinstalling Windows or are working on a different PC.

Before proceeding, back up your files and confirm the device’s Windows 11 hardware requirements. Microsoft warns that installing Windows on unsupported hardware can cause compatibility problems and may leave the device unsupported and ineligible for updates.

If you only want to move an eligible PC from 24H2 or 25H2 to 26H2, use Windows Update first. A manual installation is not automatically better just because it offers more control.

How to fix common Windows 11 26H2 installation problems

If the update appears but fails to download or install, treat that as a different problem from an update that is not offered. The first calls to action should be the Windows Update troubleshooter and Microsoft’s error-specific guidance.

Windows Update download or installation errors

Microsoft recommends using the Windows Update troubleshooter in the Get Help app on Windows 11. You can also find the troubleshooter under Settings → System → Troubleshoot → Other troubleshooters → Windows Update on supported Windows 11 interfaces.

Follow this recovery sequence:

1. Run the Windows Update troubleshooter and apply its recommendations.
2. Confirm that your internet connection is stable.
3. Restart the PC.
4. Return to Windows Update and check again.
5. If the installation still fails, record the exact error code and use Microsoft’s Windows Update troubleshooting guide.

An exact error code is more useful than a generic message that the update failed. Different codes can indicate network, service, storage or installation problems, so avoid applying a random fix that does not match the error.

Insufficient storage or a pending restart

If Windows reports that there is not enough space, free storage by removing files you no longer need, uninstalling unused apps or moving personal files to another drive. Back up important data before deleting anything.

If Windows has already installed updates that require a restart, complete that restart before trying again. Windows Update may not proceed normally while an earlier update remains pending. See Microsoft’s Windows Update FAQ for additional storage and restart guidance.

The update fails repeatedly or rolls back

If Windows repeatedly fails to complete the upgrade, do not keep rerunning the same process indefinitely.

• Record the error code and any message displayed during the rollback.
• Check release health for known issues affecting your version or device.
• Install the latest applicable servicing updates.
• If the problem continues, follow Microsoft’s upgrade-error guidance or contact Microsoft support.

A rollback can be a protective response to an installation problem. Avoid disabling safeguards or making unverified registry changes to force the upgrade.

How to confirm Windows 11 26H2 installed successfully

After Windows restarts, verify the version instead of assuming the installation completed.

Check the Windows version and OS build

1. Press Windows + R.
2. Enter winver and press Enter.
3. Check the version displayed in the About Windows dialog.

The dialog should identify Version 26H2 if the upgrade succeeded. You can also open Settings → System → About to inspect the Windows specifications and OS build.

Check Windows Update for remaining updates

Open Settings → Windows Update and select Check for updates. Install any applicable updates and restart if prompted. Keeping Windows current after a feature update helps ensure that you receive later fixes and security improvements.

If something stops working after the upgrade, check Microsoft’s current release-health page and install available fixes before attempting a rollback or reinstall.
