How to Check Windows 11 Version and Build Number

Knowing your Windows 11 version and build number can help you troubleshoot problems, check compatibility with software, and determine whether your computer has received a particular Windows update. Microsoft regularly releases feature updates, security updates, and other improvements, so two computers running Windows 11 may have different versions and builds.

Checking this information is also useful when following troubleshooting guides. Some Windows features are available only in specific releases, and the Settings interface can change between updates. Providing your exact version and build number can help technical support identify the configuration you are using.

Windows 11 offers several ways to find these details. You can use the Settings app, the Winver command, Command Prompt, PowerShell, or System Information. Each method displays slightly different information, depending on the tool.

In this guide, you will learn how to check your Windows 11 version, edition, OS build number, and system details. You will also learn how to understand the information displayed and what to do if your computer is running an older version of Windows 11.

Method 1: Check Windows 11 Version in Settings

The Settings app is the easiest way to find your Windows 11 version and build number. It also displays your Windows edition and other operating system information.

Follow these steps:

1. Press Windows + I to open Settings.
2. Select System from the left sidebar.
3. Scroll down and click About.
4. Find the Windows specifications section.
5. Review the information displayed.

Under Windows specifications, you will typically find:

• Edition: The installed edition, such as Windows 11 Home or Windows 11 Pro.
• Version: The Windows feature release installed on your computer.
• Installed on: The date Windows records as the installation date.
• OS build: The operating system build number.
• Experience: The Windows Feature Experience Pack version, when displayed.

For example, a computer might display Windows 11 version 24H2 with an OS build such as 26100.xxxx. The final digits can vary because cumulative updates change the build number.

Your computer may show a different version depending on its update history and eligibility for newer releases.

This method is particularly useful when you need to share your system details with technical support or confirm whether your computer is running a particular feature update.

Method 2: Use the Winver Command

The Winver command opens a small About Windows window that displays the Windows version and OS build information.

Follow these steps:

1. Press Windows + R to open the Run dialog.
2. Type the following command:winver
3. Press Enter.
4. Wait for the About Windows window to appear.
5. Read the version and OS build information.

The window identifies the installed Windows version and displays the operating system build. Depending on the release, it may also show licensing information.

This method is convenient because you do not need to navigate through Settings.

You can use Winver when troubleshooting software compatibility or checking whether an instruction applies to your version of Windows 11.

However, the Winver window does not provide every system detail. If you also need the Windows edition, installation date, or Windows Feature Experience Pack version, open Settings and navigate to System > About.

Method 3: Check the Windows Build Number Using Command Prompt

Command Prompt can display the Windows version and build information through built-in commands.

Follow these steps:

1. Open the Start menu.
2. Search for Command Prompt.
3. Open the application.
4. Enter the following command:ver
5. Press Enter.

Windows will display a version string containing the operating system build information.

For a more detailed report, run:

systeminfo

Press Enter and wait for the system information report to appear.

Look for entries such as OS Name, OS Version, and System Type. The report may also include information about the system manufacturer, processor, memory, and Windows installation.

The systeminfo command can take a little longer to complete because it collects multiple details about the computer.

If you only need the Windows build number, ver is quicker. If you need additional operating system and hardware information, systeminfo is more useful.

Keep in mind that command output may display version numbers in a format that differs from the friendly version name shown in Settings.

Method 4: Find Windows 11 Version Using PowerShell

PowerShell provides another way to inspect Windows version and build information. This method is useful for users who prefer command-line tools or want to collect system details for troubleshooting.

Follow these steps:

1. Open the Start menu.
2. Search for PowerShell or Windows Terminal.
3. Open the application.
4. Enter the following command:Get-ComputerInfo | Select-Object WindowsProductName, WindowsVersion, OsBuildNumber
5. Press Enter.
6. Review the displayed information.

The command requests the Windows product name, version, and operating system build number.

You may also run the following command to retrieve the operating system version details from the Windows registry:

Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' | Select-Object ProductName, DisplayVersion, CurrentBuild, UBR

This command displays the product name, display version, current build, and update build revision.

The CurrentBuild value identifies the main build number, while UBR represents the update build revision. These values can help you identify the more specific build installed on your computer.

PowerShell output may differ slightly across Windows releases. For the easiest interpretation, compare the results with the Windows specifications shown under Settings > System > About.

Method 5: Check Windows Version Using System Information

System Information is a built-in Windows utility that provides details about the operating system, hardware, and system configuration.

Follow these steps:

1. Press Windows + R.
2. Type:msinfo32
3. Press Enter.
4. Wait for the System Information window to open.
5. Make sure System Summary is selected.
6. Find the OS Name and Version entries.

The OS Name entry identifies the installed Windows edition or product name. The Version entry provides operating system version and build information.

System Information also displays details such as the system manufacturer, model, processor, BIOS mode, installed physical memory, and system type.

This makes it useful when you need to check Windows version alongside hardware details. For example, you may need both the OS build and system architecture when troubleshooting a driver installation.

If you are checking compatibility with a particular application, review the application’s system requirements and compare them with the information displayed by System Information.

Method 6: Understand Windows 11 Version and Build Numbers

Windows version numbers and build numbers identify different aspects of the operating system.

The version generally refers to a feature release, such as 23H2 or 24H2. Feature releases introduce changes and may add new functionality.

The OS build number identifies the underlying Windows build. For example, Windows 11 version 24H2 uses the 26100 build family. Cumulative updates can change the revision portion of that build number.

Consider an example where Windows displays version 24H2 and OS build 26100.5000. In this example:

• 24H2 is the feature release.
• 26100 is the main OS build.
• 5000 is an illustrative update revision, not a guarantee of the latest revision.

The exact build and revision installed on your computer depend on the updates it has received.

The Windows edition is a separate detail. Windows 11 Home and Windows 11 Pro can share the same feature version and build while offering different features and administrative capabilities.

The Windows Feature Experience Pack is another component that may appear in the About page. Its version does not replace the main Windows version or OS build number.

When reporting your system configuration, include both the Windows version and complete OS build when possible. This provides more precise information than saying only that you are using Windows 11.

Method 7: Check Whether Windows 11 Is Up to Date

After checking your Windows version, you may want to determine whether updates are available for your computer.

Follow these steps:

1. Press Windows + I.
2. Select Windows Update.
3. Click Check for updates.
4. Wait while Windows checks for available updates.
5. Review the results.
6. Install applicable updates if appropriate.
7. Restart the computer if required.

Windows Update may offer security updates, cumulative updates, driver updates, or feature updates depending on your device and Microsoft’s rollout policies.

A computer does not necessarily need to display the newest possible version number to be fully updated for its current configuration. Feature updates can be offered gradually, and compatibility safeguards may delay an update on some devices.

You should also distinguish between being up to date and using a supported Windows release. Check Microsoft’s current lifecycle information if you need to confirm the support status of a particular version.

If an update is unavailable, do not immediately assume something is wrong. Check for error messages, compatibility notices, and any updates that require a restart.

Method 8: Troubleshoot Incorrect or Missing Version Information

Sometimes, Windows version information may be confusing or differ between tools. This can happen because the tools display different details or because Windows has not completed an update.

Try these checks if the information looks incorrect.

Restart your computer. If an update was installed recently, a restart may be required before all version information reflects the updated system state.

Check multiple locations. Compare Settings > System > About with the output from winver and systeminfo.

Install available updates. Open Windows Update and review any pending updates or restart requirements.

Confirm the Windows edition. Settings may show Home, Pro, or another edition. This is separate from the feature version and build number.

Check the complete build number. A main build number without its update revision may not identify the exact cumulative update level.

Investigate update errors. If Windows Update repeatedly fails, record the error code and troubleshoot the update problem rather than attempting to change the version information manually.

Avoid editing Windows registry values to change the displayed version. Registry edits do not upgrade Windows and can cause configuration problems.

If you need a specific Windows version for software compatibility, check the software vendor’s requirements before attempting to change your operating system release.

Conclusion

Checking your Windows 11 version and build number is a simple but useful troubleshooting task. It helps you identify the feature release installed on your computer, determine the operating system build, and provide accurate information when requesting technical support.

The easiest method is to open Settings, navigate to System > About, and review the Windows specifications section. If you need a quick result, run winver through the Run dialog. Command Prompt, PowerShell, and System Information provide additional ways to inspect operating system details.

Remember that the Windows edition, feature version, main build number, and update revision are different pieces of information. For precise troubleshooting, record the version and complete OS build rather than relying only on the Windows 11 product name.

You can also check Windows Update to review available updates. If a feature update is not offered, your device may be subject to compatibility safeguards or a gradual rollout. Confirm the support status of your installed version when security updates and long-term compatibility are important.
