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 11, Windows 10, or an older version. Below that, Version shows the specific build number, and OS Build shows the exact update level your computer is running.

If you prefer not to open Settings, you can also right-click the Windows logo in the bottom left corner of your screen, select System, and you'll land on the same About page.

Key Takeaways

  • Settings > System > About shows your Windows edition, version number, and OS build in one place.
  • The Edition line tells you if you have Windows 11, Windows 10, or an older version; Version and OS Build show how current your updates are.
  • You can also reach this information by right-clicking the Windows logo and selecting System.
  • Knowing your OS version matters when downloading software, troubleshooting problems, or checking if your computer can run a new program.

Why your Windows version number matters

Different software requires different Windows versions. A program built for Windows 11 might not run on Windows 10, and older programs sometimes won't work on the newest Windows. When you download something and it doesn't install, the first thing to check is whether your Windows version matches what the software needs.

Your OS Build number also tells you whether you're up to date with security patches. Windows releases updates regularly, and each one gets a new build number. If your build number is months behind, your computer may be missing important security fixes. You can compare your build number to Microsoft's official list to see how current you are.

Using the Run command for a faster check

If you want to skip Settings entirely, press Windows key + R to open the Run dialog box. Type winver and press Enter. A window will pop up showing your Windows edition, version, and OS build number in a simple format.

This method is faster if you just need the information once and don't want to navigate through menus. The information displayed is identical to what you'd see in Settings — just presented differently.

Understanding what each number means

The Edition is the broadest category: Windows 11 Home, Windows 11 Pro, Windows 10 Home, and so on. Home editions have fewer features than Pro editions, but both run the same core operating system. If you're not sure which edition you have, this is the line that answers it.

The Version number (like 23H2 or 22H2) represents a major update cycle. Windows releases new versions roughly once a year, and each version includes new features and improvements. The OS Build is more granular — it changes with smaller updates that happen monthly or as needed for security patches. A build number like 22621.3737 means you're on version 22H2 with additional patches applied on top.

Checking if you need to update

Once you know your OS Build number, you can check Microsoft's official Windows release information page to see if newer builds are available. If your build is significantly older than the current one, Windows Update may have missed running, or your computer may need to be restarted to finish an update.

To manually check for updates, open Settings, go to System, and click Windows Update in the left menu. Click Check for updates and Windows will scan for any available patches. If updates are found, you can install them immediately or schedule them for later.

Version information for older Windows systems

If you're running Windows 8, Windows 7, or an even older version, the process is slightly different. Right-click This PC or My Computer on your desktop, select Properties, and your Windows version will appear in the window that opens. You can also press Windows key + Pause/Break to open the same Properties window directly.

Older Windows versions no longer receive security updates, so if you're using Windows 7 or earlier, consider upgrading to a newer version. Microsoft stopped supporting Windows 7 in 2020 and Windows 8 in 2016, meaning no new security patches are released for them.

Frequently Asked Questions

What's the difference between Version and OS Build?

Version is the major release cycle (like 23H2), released roughly once a year. OS Build is the specific patch level within that version, updated monthly or as needed for security fixes. You need both numbers to know exactly what you're running.

Can I check Windows version from the command line?

Yes. Open Command Prompt or PowerShell and type systeminfo, then press Enter. Scroll to find "OS Version" and "System Boot Time" — the OS Version line shows your Windows edition and build number in technical format.

Why does my version number look different from my friend's?

Windows rolls out updates in waves, so different computers get new versions on different dates. Your friend's computer may have installed the latest update already while yours is still pending, or vice versa. Both are normal.

Does knowing my Windows version help with troubleshooting?

Yes. When you search for help with a problem, including your Windows version helps you find solutions that actually apply to your system. Some bugs affect only certain versions, so knowing which one you have narrows down the cause.

What if Settings shows a version I don't recognize?

Windows uses version numbers like 22H2 or 23H2 (the H stands for "half-year"). If you see a number you don't recognize, it's still a real Windows version — Microsoft just uses this naming system internally. Your OS Build number is more specific and easier to look up if you need details.
