The fastest 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 — that tells you whether you have Windows 11, Windows 10, or an older version. The same screen also shows your OS Build, which is the specific update number within that version.

If Settings doesn't open, you can also right-click the Windows logo in the bottom left corner of your screen and select System directly. This takes you to the same About page.

On older computers running Windows 7 or earlier, the Settings app may not exist. Instead, right-click This PC or My Computer on your desktop, select Properties, and look for the version name near the top of the window.

Key Takeaways

  • Your Windows version appears in Settings > System > About under the line labeled Edition.
  • The OS Build number on the same screen tells you which update you have installed within your version.
  • You can also reach this information by right-clicking the Windows logo and selecting System.
  • Knowing your version matters because some programs and updates only work on specific Windows editions.

Why your Windows version matters

Different programs and security updates only work on certain Windows versions. If you're trying to install software and it says your system isn't compatible, the version number tells you whether you need to upgrade your operating system or find an older version of the program instead.

Microsoft also stops supporting older Windows versions at specific dates. Windows 10 support ends in October 2025, for example, which means no more security updates after that date. Knowing which version you have tells you how much longer your computer will receive protection against new threats.

Understanding the difference between Edition and Build

The Edition is the main version name: Windows 11, Windows 10, Windows 8, or Windows 7. This is what most people mean when they ask "what version of Windows do you have?"

The OS Build is a longer number like 22621.2715 that represents a specific update within that edition. Microsoft releases new builds regularly to fix bugs and add security patches. Two computers can both run Windows 11 but have different build numbers if one was updated more recently than the other.

You usually don't need to know your build number unless you're troubleshooting a specific problem or checking whether a particular security patch has been installed on your computer.

What to do if you see an unfamiliar version name

Windows has several edition types within each main version: Home, Pro, Enterprise, and Education are the most common. Home is the standard version sold to regular consumers. Pro includes extra features like remote desktop and BitLocker encryption. Enterprise and Education versions are only for businesses and schools.

If your Edition line shows something like "Windows 11 Pro" or "Windows 10 Home", the word after the number tells you which edition you own. This matters because some features and settings are only available in Pro or higher editions. If you need a feature that's locked to Pro, you would need to purchase an upgrade.

Checking Windows version on a network or shared computer

If you use a computer at work or school, you may not have permission to access Settings. Ask your IT department or network administrator for your Windows version instead — they have records of every computer on the network and can tell you in seconds.

If you have limited user access but still need the information, try pressing Windows key + R to open the Run dialog, type winver, and press Enter. This opens a small window showing your version and build number. This method sometimes works even when the full Settings app is restricted.

Keeping track of your Windows version over time

Windows updates happen automatically on most computers, and your build number changes each time. If you need to remember your current version for support purposes, take a screenshot of the About page or write down the Edition and Build number in a document you can find later.

You can also check Windows Update history to see when your computer last received an update. In Settings, go to Update & Security (Windows 10) or System > Windows Update (Windows 11), then look for Update History or See your update history. This shows you the date and build number of each update installed.

Frequently Asked Questions

Can I upgrade from Windows 10 to Windows 11?

Windows 11 has specific hardware requirements, including a compatible processor and at least 4 GB of RAM. Not all computers that run Windows 10 can upgrade to Windows 11. Check your current system information first, then visit Microsoft's official Windows 11 system requirements page to see if your computer qualifies.

What if Settings shows a build number but no Edition name?

This usually means your Windows installation is incomplete or corrupted. Try restarting your computer and checking again. If the Edition line remains blank, your system may need a repair or reinstall. Contact Microsoft Support or a local computer technician for help.

Does my Windows version affect which programs I can install?

Yes. Some software only runs on Windows 10 or newer, while older programs may not work on Windows 11. Always check the program's system requirements before downloading. The requirements list will specify which Windows versions are supported.

Is there a difference between Windows 11 Home and Windows 11 Pro for everyday use?

Home and Pro run the same core system, but Pro includes features most people don't need: remote desktop access, BitLocker encryption, and Group Policy settings. For browsing, email, and everyday work, Home is sufficient. You only need Pro if your job or specific software requires those extra features.
