Windows 11 26H2: How to Verify the Version Installed on Your PC

Find the installed Windows 11 version in Settings or with winver. Version 26H2 confirms the update; the full OS build can change with monthly servicing.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

To check whether Windows 11 26H2 is installed, open Settings > System > About and look under Windows specifications. If the Version field says 26H2, that is the installed version. You can also run the built-in winver tool.

Check the version in Settings

  1. Select Start > Settings.
  2. Open System > About.
  3. Scroll to Windows specifications and read the Version field. 26H2 means Windows 11 26H2 is installed.

The same section shows the OS build. Microsoft’s Windows version-identification guidance documents this About page as the place to check which Windows version is running.

Use winver as a quick alternative

  1. Search the taskbar for winver.
  2. Open the result to display the About Windows dialog.
  3. Read the version shown in the dialog. If it says Version 26H2, 26H2 is installed.

This built-in check is useful when you want a compact version display instead of navigating through Settings.

Why the OS build number is not the main check

Microsoft identifies Windows 11 26H2 with OS build family 26300, but the full build number can change as monthly updates are installed. Use the Version label to determine whether 26H2 is installed; the OS build provides more specific servicing information, not a single permanent proof number. See Microsoft’s Windows 11 release information.

If your PC shows a different version

If Settings or winver shows a version other than 26H2, that is the version currently installed. It does not, by itself, explain why 26H2 has not been offered to the PC. Microsoft reported 26H2 generally available on September 29, 2026, with a phased rollout to eligible Windows 11 24H2 and 25H2 devices; availability for a particular PC depends on rollout and eligibility. Microsoft maintains 26H2 known issues and notifications for further rollout information.
