The fastest way to find your Windows version

Open the Settings app by pressing the Windows key and typing "settings", then click the result. In Settings, select System on the left side, then scroll down and click About. Look for the line that says Edition — this tells you whether you have Windows 11, Windows 10, or an older version. Below that, you'll see Version, which is a number like 23H2 or 22H2. Write both down if you need them later.

If Settings doesn't open or feels slow, you can use the keyboard shortcut instead. Press Windows key + Pause/Break (the Pause key is usually in the upper right of your keyboard, sometimes labeled Pause or PrtScn). A window will open showing your Windows edition and version in the same place. This method works on almost every Windows computer and opens when ready.

A third option is to right-click the This PC or My Computer icon on your desktop or in File Explorer, then select Properties. The edition and version appear near the top of the window that opens. All three methods show the same information — use whichever feels easiest to you.

Key Takeaways

  • Your Windows edition (Windows 11, Windows 10, etc.) and version number (like 23H2) are both important, and you can find both in Settings under System > About.
  • The keyboard shortcut Windows key + Pause/Break opens the same information when ready without using Settings.
  • Your version number tells you whether you have the latest security updates, which changes roughly every few months.
  • Older versions of Windows stop receiving security updates after a certain date, so checking your version helps you know when your computer needs an upgrade.

Why your version number matters for security

The version number (23H2, 22H2, etc.) tells you whether your computer has the latest security patches. Microsoft releases updates roughly every month, and each update gets a number. If your version is several numbers behind the current one, your computer is missing security fixes that protect against known threats. You can see what the current version should be by searching online for "Windows 10 current version" or "Windows 11 current version" — Microsoft's official pages list the latest number.

Your computer should update automatically if you have Windows Update turned on, but updates sometimes stall or fail silently. Checking your version lets you know whether the updates actually installed. If you're several versions behind, go to Settings > System > Windows Update and click Check for updates. Let the computer restart if it asks — that's when the update actually installs.

The difference between editions and versions

Windows comes in different editions, and the edition you have affects what features are available and how long Microsoft supports it. Windows 11 Home is the standard edition for personal computers. Windows 11 Pro adds features for business use, like the ability to join a work domain and use BitLocker encryption. Windows 10 comes in Home and Pro as well, and some older computers still run it. A few computers have Windows 11 Enterprise or Windows 10 Enterprise, which are for large organizations.

The edition matters because Microsoft stops supporting older editions on specific dates. Windows 10 Home and Pro stop receiving updates on October 14, 2025. Windows 11 will be supported much longer, but the exact date depends on which edition you have. If your computer shows an edition that's no longer supported, it won't receive security updates anymore, even if you click "Check for updates". In that case, you would need to upgrade to a newer Windows edition or replace the computer.

What to do if your version is very old

If you check your version and it's more than a year old, your computer may have missed several rounds of updates. Start by going to Settings > System > Windows Update and clicking Check for updates. Windows will read and install any missing updates, which may take 30 minutes to an hour. Your computer will likely need to restart one or more times — let it do this, even if it interrupts what you're doing. Restarting is when the updates actually install.

After the restart, go back to Settings and check your version again. If it's still old after checking for updates twice, your computer may have a problem installing updates. In that case, you can contact Microsoft Support through the Settings app (go to System > Troubleshoot > Other troubleshooters and look for Windows Update), or take the computer to a repair shop. Don't ignore very old versions — they leave your computer vulnerable to threats that newer versions protect against.

Checking version on a work or school computer

If your computer is managed by an employer or school, the version number may be different from what you see on a personal computer. Work computers often run older versions intentionally because organizations test updates before rolling them out to everyone. Your IT department controls when updates install, not Windows Update. If you see an old version on a work computer, that's usually normal — check with your IT support before trying to update it yourself.

The same applies if your computer is part of a domain (you can see this in Settings under System > About — it will say "Domain" instead of a workgroup name). Domain computers get updates from the organization's server, not from Microsoft directly. If you're unsure whether your computer is managed, ask your IT department or supervisor before making changes to Windows Update settings.

Using version information when you need help

When you contact support — whether it's Microsoft, a software company, or a repair technician — they'll often ask what version of Windows you're running. Having this information ready saves time. Write down both your edition and your version number before you contact support. For example: "Windows 11 Home, version 23H2" or "Windows 10 Pro, version 22H2". This tells the support person exactly what you have and whether you're up to date on security updates.

If you're troubleshooting a problem with a specific program, the version number is especially useful. Some programs only work on certain Windows versions, and knowing your version helps the support person figure out whether that's the issue. You can also include a screenshot of your About page — just press Windows key + Shift + S to open the screenshot tool, select the area you want to capture, and paste it into an email or support form.

Frequently Asked Questions

Is there a difference between Windows 10 and Windows 11?

Yes — Windows 11 is newer and has different security features, a redesigned interface, and better performance on newer computers. If you have Windows 10, you can upgrade to Windows 11 for free if your computer meets the hardware requirements (mainly a compatible processor). Check your Settings to see which one you have.

What does the version number like 23H2 actually mean?

The first two digits (23) represent the year, and the H and number (H2) mean the second half of that year. So 23H2 is the second-half 2023 update. The number increases roughly every few months, so a higher number means more recent security patches.

Can I stay on an old version of Windows if I want to?

You can delay updates for a while, but eventually Microsoft stops supporting old versions completely and stops sending security patches. Once support ends, using an old version puts your computer at serious risk. It's better to update when prompted or to upgrade to a newer Windows edition before support ends.

Will checking my version slow down my computer?

No — checking your version takes a few seconds and uses almost no resources. Opening Settings or pressing the Windows key + Pause shortcut won't affect your computer's performance at all.

What if my version number doesn't match what Microsoft says is current?

Go to Settings > System > Windows Update and click "Check for updates". Windows will read any missing updates. If you're still behind after checking twice and restarting, contact Microsoft Support or a repair technician — your computer may have a problem installing updates automatically.
