The quickest way to check your Windows version

Open the Settings app by pressing the Windows key and typing "Settings", then click the result. Go to System in the left menu, scroll down, and click About. Look for the line that says "Edition" — that tells you whether you have Windows 10, Windows 11, or another version. You will also see your "OS Build" number on the same screen, which is the specific update level of your Windows installation.

If you need this information right now and do not want to open Settings, you can also press Windows key + R, type winver, and press Enter. A small window will pop up showing your version and build number when ready. Both methods take less than 30 seconds.

Key Takeaways

  • The Settings app's About section shows your Windows edition and build number in one place.
  • The winver command is the fastest route if you just need to see the version once and close it.
  • Your build number changes with each Windows update, so checking it tells you whether your computer has the latest patches.
  • Knowing your Windows version matters when you are troubleshooting problems or checking whether a program will run on your computer.

Why you need to know your Windows version

Your Windows version determines which programs will run on your computer and which security updates you receive. Windows 10 and Windows 11 are different enough that software written for one may not work on the other. If you are having a problem and you search for a solution online, the answer often depends on which version you have — the steps to fix something in Windows 11 can be completely different from Windows 10.

Your build number is equally important. Windows releases updates regularly, and each one gets a new build number. If you are missing a recent update, your build number will be older than the current one. Checking your build number tells you whether your computer has the latest security patches, which is one of the most important things you can do to keep it running safely.

Using the Settings app method

This is the most reliable way because it shows you everything in one screen. Press the Windows key (the key with the Windows logo on it) and start typing "Settings". When the Settings app appears in the results, click it. The Settings window will open.

On the left side of the Settings window, you will see a menu. Click on System. The main area will show several options. Scroll down until you see About and click it. The About page displays your Windows edition at the top, along with your device name, processor, RAM, and build number. The "Edition" line is what you are looking for — it will say something like "Windows 10 Home" or "Windows 11 Pro".

Write down your build number if you need it for troubleshooting. It appears on the same screen as a long number like "22621.1234". This number tells you exactly which update level your computer is on, which is useful when you are comparing your setup to someone else's or checking whether you need to install new updates.

Using the winver command for a quick check

If you do not want to navigate through Settings, the winver command is faster. Press Windows key + R at the same time. A small box called "Run" will appear. Type winver (all lowercase) and press Enter. A window titled "About Windows" will pop up when ready.

This window shows your Windows version, your build number, and your system information all at once. It is smaller and simpler than the Settings method, but it shows you the same information. Close the window when you are done by clicking the X button. This method is especially useful if you just need to check your version once and do not need to change any settings.

Understanding what the version numbers mean

Windows comes in different editions, and the edition you have affects which features are available. Windows 10 Home is the standard version for most home computers. Windows 10 Pro adds features for small businesses and advanced users. Windows 11 Home and Windows 11 Pro follow the same pattern but are the newer version of Windows.

The build number is separate from the edition. It looks like a long number such as "22621.1234" and changes every time Microsoft releases an update. The first part of the build number (like "22621") tells you which major update you are on. The second part (like "1234") tells you which smaller update within that major release. If your build number is older than what you see on Microsoft's website for your version, your computer needs updates.

What to do if you cannot find your version

If the About screen does not show your Windows version clearly, or if you see an error message, your Windows installation may be damaged or incomplete. Try restarting your computer first — sometimes the Settings app does not load correctly until after a restart. After restarting, try the winver command again.

If you still cannot see your version, try opening File Explorer (press Windows key + E), right-click on "This PC" in the left menu, and select Properties. An older-style window will open showing your system information, including your Windows version. This method works on almost all Windows computers, even older ones or ones with Settings problems.

Checking for updates after you know your version

Once you know your build number, you can check whether your computer needs updates. Open Settings again and go to System, then click Windows Update (it is above the About option). Click Check for updates. Windows will connect to Microsoft's servers and tell you whether new updates are available. If updates are available, click read and install. Your computer may restart during this process, so close any open programs first.

Checking your version and keeping your computer updated are two of the most important things you can do to keep Windows running smoothly and safely. Updates fix security problems, improve performance, and add features. Most updates install automatically, but checking manually once a month ensures you do not fall behind.

Frequently Asked Questions

What is the difference between Windows 10 and Windows 11?

Windows 11 is the newer version with a redesigned interface and some new features, but Windows 10 still receives security updates. If your computer is running Windows 10, it will continue to work fine. Windows 11 requires newer hardware on most computers, so not all older machines can upgrade.

Why does my build number keep changing?

Your build number changes every time Windows installs an update. These updates fix security problems and improve performance. Checking your build number tells you whether your computer has the latest patches. If your build number is very old, your computer may be missing important security fixes.

Can I change my Windows edition from Home to Pro?

Yes, but you have to purchase a license from Microsoft. You cannot change editions through Settings alone. Go to Settings, System, About, and look for an option that says "Upgrade your edition" or "Change product key". You will need to buy a Pro license key from Microsoft or an authorized retailer.

What if my computer says "Windows N" or "Windows KN"?

These are special editions sold in certain countries. Windows N means your version does not include Windows Media Player, and Windows KN means it does not include certain multimedia features. They work the same way as regular Windows otherwise, and you check the version the same way.

Do I need to restart my computer after checking the version?

No. Checking your version does not change anything on your computer — it only shows you information. You only need to restart if you are installing updates or if Windows asks you to restart after an update finishes.
