The quickest way to check your Windows version

Open the Settings app by pressing the Windows key and typing "Settings", then select it from the results. Go to System in the left menu, scroll down, and click About. Look for the line that says "Edition" — this tells you whether you have Windows 11, Windows 10, or an older version. The same screen shows your build number, which is useful if you need to troubleshoot a specific problem or check whether you have the latest updates.

If Settings does not open or you prefer a faster method, press Windows key + R, type winver, and press Enter. A window will pop up showing your Windows version, build number, and the date your system was last updated. This method works on every Windows version from Windows 7 forward.

Key Takeaways

  • Your Windows version appears in Settings under System > About, listed as the "Edition" line.
  • The winver command opens a quick popup showing your version and build number without navigating menus.
  • Your build number matters for troubleshooting — different builds have different fixes and known issues.
  • Knowing your version helps you understand which features your computer can run and whether you need to update.

Why your Windows version matters

Your version determines what features your computer can use and what support is available. Windows 11 runs newer software and security tools that Windows 10 cannot handle. Windows 10 reaches end of support in October 2025, meaning Microsoft will stop releasing security updates after that date. If you are still on Windows 7 or Windows 8, your system no longer receives any updates at all, which leaves it vulnerable to viruses and malware.

The build number within your version also matters. Microsoft releases updates monthly, and each one gets a new build number. If you report a problem to support or search for a fix online, knowing your exact build number helps you find solutions that explore to your specific situation. Two people on Windows 11 might have different builds and experience different bugs or have access to different fixes.

Finding your version through System Information

For more detailed information than the About screen shows, open System Information. Press Windows key + R, type msinfo32, and press Enter. This window displays your OS name, version, build, and system manufacturer all in one place. It also shows your processor, RAM, and other hardware details, which is useful if you are troubleshooting performance problems or checking whether your computer meets the requirements for new software.

System Information is especially helpful if you need to share your version details with technical support. You can take a screenshot of this window and send it to whoever is helping you, and they will see everything they need at once.

Checking your version on older Windows systems

If you are running Windows 7, Windows Vista, or Windows XP, the process is slightly different. Right-click My Computer or This PC on your desktop, select Properties, and your version appears near the top of the window. You can also press Windows key + Pause/Break to open the same screen directly.

However, if you are on Windows 7 or older, you should plan to update your system. These versions no longer receive security patches, which means new viruses and malware can infect your computer without protection. Windows 10 or Windows 11 will run faster on most modern hardware and keep your files safer.

Understanding Windows editions

Windows comes in different editions, and your version screen tells you which one you have. Windows Home is the standard version for personal computers. Windows Pro adds features for small businesses, like the ability to join a company network and use remote desktop. Windows Enterprise is for large organizations. Most home users have Windows Home and do not need to worry about the difference.

Your edition affects what you can do with your computer, but it does not change how you find your version. The edition name appears right next to the version number in Settings.

What to do after you find your version

Once you know your version, check whether you need to update. Open Settings, go to System, and click Windows Update on the left. Click Check for updates and let your computer read and install any available patches. Updates fix security problems and improve performance, so running the latest build of your version keeps your system safer and faster.

If your version is Windows 7 or older, or if Windows 10 is approaching its end-of-support date, consider upgrading to Windows 11. You can check whether your hardware supports Windows 11 by downloading the PC Health Check app from Microsoft's website — it will tell you whether your processor, RAM, and storage meet the requirements.

Frequently Asked Questions

What is the difference between version and build number?

Version is the major release, like Windows 10 or Windows 11. Build number is the specific update within that version. Windows 10 version 22H2 build 19045 means you are on Windows 10's latest version with a specific monthly update applied. The build number changes more often than the version.

Can I upgrade from Windows 10 to Windows 11 for free?

Yes, if your hardware meets the requirements. Windows 11 is a free upgrade from Windows 10. Use the PC Health Check app to see whether your processor, RAM, and storage are compatible. If your computer does not meet the requirements, you can stay on Windows 10 until October 2025 when support ends.

Why does my version number have letters and numbers like 22H2?

Microsoft changed how it names Windows 10 updates. The "22" refers to 2022, and "H2" means the second half of the year. This naming system helps you understand when an update was released. Windows 11 uses the same system.

Is it safe to update to the latest build?

Yes. Monthly updates fix security problems and bugs. Delaying updates leaves your computer vulnerable to viruses. If an update causes problems, you can roll back to the previous build through Settings > System > Recovery, though this is rarely necessary.

What if winver does not work on my computer?

Try opening Settings directly and navigating to System > About instead. If Settings will not open, restart your computer and try again. If the problem persists, your Windows installation may be corrupted, and you may need to reinstall Windows or contact technical support.
