Where to find your Windows version number

Your Windows version is a specific number that tells you which release of Windows you are running — Windows 10, Windows 11, or an older version. You need this number when troubleshooting problems, checking if your device can run new software, or understanding what security updates your system receives. The fastest way to find it is through the Settings app, which takes about 30 seconds.

Open Settings by pressing the Windows key and the letter I at the same time, or by right-clicking the Start button and selecting Settings. Once Settings opens, look at the left sidebar and click System. Then scroll down and click About. Your Windows version appears on the right side under "Edition" — it will say Windows 10 or Windows 11. Below that, you will see "Version" with a number like 23H2 or 22H2. That version number tells you which update level you are on.

Key Takeaways

  • Your Windows version number appears in Settings under System > About, and shows both your Windows edition (10 or 11) and your current update level.
  • The version number matters because older versions stop receiving security updates, and some software requires a minimum version to run.
  • You can also find your version by typing "winver" into the search box and pressing Enter, which opens a small window with all the details at once.
  • If you see a version number older than a few years, Windows Update may have new patches waiting, which you can check in Settings > Update & Security.

Using the winver command for a quick view

If you want to see your version in a single small window instead of navigating through Settings, use the winver command. Click the search box at the bottom left of your screen (or press the Windows key and type), then type winver and press Enter. A window titled "About Windows" will open when ready, showing your Windows edition, version number, and build number all in one place.

This method is useful when you need to read the information quickly or take a screenshot to send to someone helping you troubleshoot. The build number — a longer string of digits below the version — is sometimes what technical support will ask for, so having this window open saves you a second trip to Settings.

Understanding what your version number means

Windows version numbers follow a pattern. If you see "Windows 11, Version 23H2," the "23H2" means the update from the second half of 2023. If you see "Windows 10, Version 22H2," that is the update from the second half of 2022. The higher the number, the more recent your update. This matters because Microsoft stops supporting older versions — Windows 10 support ends in October 2025, meaning no new security patches after that date.

The build number is a longer code like "22621.2715." You do not need to understand it, but it is the exact identifier of your system's state. If you contact support or post in a forum, providing your build number helps others know exactly what you are running, because two people on "Windows 11" might have slightly different builds with different bugs or fixes.

Checking if your version is up to date

Once you know your version number, you can check whether Windows has newer updates waiting. Go back to Settings, click System, then click Update & Security (on Windows 10) or Windows Update (on Windows 11). Click the button that says "Check for updates." Windows will scan for any patches or version upgrades available for your device.

If updates are found, Windows will read them automatically and ask you to restart your device. You do not have to restart when ready — you can choose a time that works for you, though Windows will eventually require the restart. Keeping your version current is important because each update includes security fixes that protect your device from threats.

Why your version matters for software and security

Some programs and games require a minimum Windows version to run. If you try to install something and get an error saying your version is too old, you now know where to check what you have. Similarly, if you are having a technical problem, knowing your exact version helps you search for solutions that explore to your specific setup — a fix for Windows 11 Version 23H2 might not work on Windows 10.

Security is the main reason to keep track of your version. When Microsoft stops supporting a version, it stops releasing security patches for it. Running an unsupported version leaves your device vulnerable to new threats. If you see that your version is more than a year old, running Windows Update is worth doing soon.

Finding your version on older Windows systems

If you are running Windows 7, Windows 8, or an older version, the steps are slightly different. Press the Windows key and the Pause key at the same time, or right-click "This PC" or "My Computer" on your desktop and select Properties. A window will open showing your Windows edition at the top. You can also type "winver" in the search box, which works on all Windows versions.

Note that Windows 7 support ended in January 2020, and Windows 8 support ended in January 2016. If you are running either of these, your device is no longer receiving security updates. Upgrading to Windows 10 or Windows 11 is strongly recommended if your hardware can support it, because an unsupported system is at serious risk from malware and other threats.

Frequently Asked Questions

What is the difference between Windows edition and version number?

Edition is the type of Windows you have — Windows 10 Home, Windows 10 Pro, Windows 11 Home, or Windows 11 Pro. Version is the update level within that edition — all Home and Pro editions of Windows 11 can be on Version 23H2. You need both pieces of information for some troubleshooting, but version matters more for security updates.

Does my version number affect how fast my computer runs?

Not directly. A newer version might run slightly faster or slower depending on the specific update, but the difference is usually not noticeable. What matters more is keeping your version current for security. An older, unsupported version is more likely to get infected with malware, which will definitely slow your computer down.

Can I downgrade to an older Windows version?

Downgrading is possible but complicated and not recommended. Windows is designed to move forward through updates. If you downgrade, you lose security patches and may lose access to features. If you are having problems with your current version, updating to the latest version usually fixes them rather than going backward.

What should I do if Windows Update says my version is up to date but I see an older version number?

Your version number might be a few months old and still be fully supported — Microsoft releases updates gradually, so not all devices get the newest version on the same day. If Windows Update says you are up to date, you are receiving all available patches for your device. You do not need to do anything.

Is there a way to see my version history or when I last updated?

Windows does not show a detailed history in Settings, but you can see when the last update installed by going to Settings > System > About and looking at the "Last checked for updates" date. For a more detailed log, you can open Event Viewer by typing "eventvwr" in the search box, but that requires reading technical logs and is not necessary for most users.
