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 Home, Windows 11 Pro, Windows 10 Home, or another version. The number next to "Version" shows which release you're on (like 23H2 or 22H2).

If you prefer not to open Settings, you can also right-click the Start button, select Run, type winver, and press Enter. A window will pop up showing your edition and version number in plain language.

Both methods take about 30 seconds and show you everything you need to know about what you're running.

Key Takeaways

  • Settings > System > About is the standard way to find your Windows edition and version number.
  • The "Edition" line tells you if you have Home, Pro, Enterprise, or another variant.
  • The "Version" number (like 23H2) shows which release update you're on.
  • You can also type winver into the Run dialog to see the same information in a popup window.
  • Knowing your exact version matters because some programs and security updates only work on certain editions.

What the numbers and names actually mean

Windows comes in different editions, and the one you have depends on when you bought your computer or which version you installed. Home is the standard edition that comes on most new computers. Pro includes extra features like the ability to join a business domain and use Remote Desktop. Enterprise is for large organizations. If you see "Education" or "S Mode", those are specialized versions for schools or specific use cases.

The version number (23H2, 22H2, and so on) tells you which update cycle you're on. Microsoft releases major updates twice a year, usually in spring and fall. The "H" stands for "half-year", so 23H2 means the second half of 2023. This matters because older versions eventually stop receiving security updates, usually about 18 months after release.

You may also see a "Build" number, which is even more specific — it's the exact internal version of Windows running right now. You don't usually need to know this unless you're troubleshooting a specific problem with Microsoft support.

Where to look if Settings doesn't show what you need

Sometimes the About page in Settings doesn't show everything you're looking for. If you need the full build number or want to see your system information in more detail, right-click the Start button, select Run, type msinfo32, and press Enter. This opens System Information, which lists your edition, version, build number, and hardware details all in one place.

Another option is to right-click This PC or My Computer on your desktop or in File Explorer, then select Properties. On older Windows 10 systems, this shows your edition and some version information, though it's less detailed than the Settings app.

Checking if you're on the latest version

Once you know your version number, you can check whether Microsoft is still sending updates to it. Windows 10 Home and Pro receive updates for about 21 months after each version releases. Windows 11 Home and Pro receive updates for 24 months. If your version is older than that window, you should update to a newer one.

To update Windows, go to Settings > Update & Security (on Windows 10) or Settings > System > Windows Update (on Windows 11), then click Check for updates. Windows will read and install the latest version available for your edition. You may need to restart your computer, and the process can take 20 minutes to an hour depending on how far behind you are.

If you see a message saying you're already on the latest version, you're receiving current security updates. If the version number is more than two years old, you may want to check whether your computer can upgrade to Windows 11, since Windows 10 support ends in October 2025.

Why knowing your version matters for programs and updates

Some software only runs on certain Windows editions. For example, Hyper-V (a tool for running virtual machines) only comes with Windows Pro and higher, not Home. Some business programs require Pro or Enterprise. Knowing your edition tells you whether a program you want to use will actually work on your computer.

Security updates also depend on your version. If you're running Windows 10 version 21H2 and it's now 2025, Microsoft has stopped sending updates to that version — you need to move to a newer one to stay protected. Checking your version regularly helps you know when it's time to update.

If you're buying a new computer or considering an upgrade, knowing what version you have now helps you understand what you'll gain or lose by switching. Home edition is cheaper but has fewer features. Pro costs more but includes tools for connecting to business networks and backing up to external drives.

What to do if you can't find your version information

If the Settings app won't open or seems broken, the winver command almost always works. Press the Windows key, type "Run", select it, type winver, and press Enter. This bypasses Settings entirely and shows your version in a straightforward popup.

If even that doesn't work, you can try opening Command Prompt (right-click the Start button and select Terminal or Command Prompt) and typing systeminfo, then pressing Enter. This shows a long list of system details, including your edition and version — look for the lines that say "OS Name" and "OS Version".

If your computer is very old or heavily damaged, these methods might not work. In that case, you can look at the Windows sticker on the back or bottom of your computer (if it's a laptop or prebuilt desktop), which usually shows the edition. Or contact the manufacturer's support line with your computer's serial number, and they can tell you what version came installed.

Frequently Asked Questions

Is Windows 11 different from Windows 10, and how do I know which one I have?

Yes, they are different operating systems. Windows 11 has a redesigned Start menu and taskbar, while Windows 10 looks different. The easiest way to tell is to look at the Start button — if it's centered on the taskbar, you have Windows 11. If it's on the left, you have Windows 10. You can also check Settings > System > About and look at the "Edition" line — it will say "Windows 11" or "Windows 10".

Can I upgrade from Windows 10 Home to Windows 11 Pro?

Yes, but it requires purchasing a license. You can't upgrade the edition (Home to Pro) for free, but you can upgrade the version (like from 22H2 to 23H2) for free. To change editions, go to Settings > System > About and click "Upgrade your edition", or purchase a Pro license key and enter it in Settings > Update & Security > set up.

What does "S Mode" mean, and should I turn it off?

S Mode is a locked-down version of Windows that only lets you install apps from the Microsoft Store. It's designed for security and speed on lower-cost computers. You can turn it off for free in Settings > System > About by clicking "Switch to Windows Home" (or Pro), but you can't turn it back on. Only switch if you need to install programs that aren't in the Store.

My version number is really old — do I need to update right away?

If your version is more than two years old, you should update soon because Microsoft has stopped sending security patches to it. Go to Settings > Update & Security (Windows 10) or Settings > System > Windows Update (Windows 11) and click "Check for updates". The update usually takes 30 minutes to an hour and requires a restart.

What's the difference between the version number and the build number?

The version number (like 23H2) tells you which release cycle you're on. The build number is more specific — it's the exact internal version. You usually only need the version number. The build number is useful if you're reporting a bug to Microsoft support or troubleshooting a very specific problem.
