The fastest way to check your Windows version

Open the Settings app by pressing the Windows key and typing "settings", then click the Settings icon. 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 Version line below it shows the specific build number, which matters if you're troubleshooting a particular problem.

If Settings doesn't open or feels slow, you can also right-click the Start button (the Windows logo in the bottom left corner) and select System directly. This skips the Settings menu and takes you straight to the same information.

Key Takeaways

  • Settings > System > About shows your Windows edition and version number in one place.
  • The Edition line tells you if you have Windows 11, Windows 10, or an older version; the Version line shows the specific build.
  • Right-clicking the Start button and selecting System is faster if your Settings app is running slowly.
  • Knowing your version matters because some updates, security patches, and software only work on specific Windows editions.

Why your Windows version matters for updates and security

Windows releases security updates on the second Tuesday of each month, but not all versions get the same updates at the same time. Windows 11 gets updates first, then Windows 10, then older versions. If you're running Windows 7 or Windows 8, Microsoft stopped releasing new security patches for those versions years ago — which means your computer is more vulnerable to viruses and malware, even if it feels fine.

Some software you want to install also requires a specific Windows version. A program might say "Windows 10 or later" or "Windows 11 only", and it straightforward won't run on an older edition. Knowing your version before you try to install something saves you the frustration of downloading a file that won't work.

Understanding Windows editions: Home, Pro, and Enterprise

The Edition line in Settings tells you not just the version number but also the type of Windows you have. Windows Home is the standard edition that comes on most personal computers. Windows Pro includes extra features like the ability to connect to a work domain and BitLocker encryption. Windows Enterprise is for large organizations and is not sold to individual users.

For most people, Windows Home is all you need. The difference between Home and Pro matters only if you're connecting to a workplace network or need advanced security features. If you're not sure which one you have, the About screen will tell you clearly.

What the version number means

Below the Edition, you'll see a Version number like "23H2" or "22H2". This is a build identifier that tells you how recent your updates are. The first two digits are the year, and the letter and number show which half of the year: H1 is the first half (January–June), and H2 is the second half (July–December). So "23H2" means the second half of 2023.

You don't need to memorize these numbers, but they're useful when you're searching for help online. If you post a question in a forum or contact support, including your version number helps the person helping you understand exactly what you're working with. You can also check the OS Build number on the same screen — that's a longer number that identifies an even more specific update.

Checking if your Windows installation is up to date

Once you know your version, you can check whether you have the latest updates. Go back to Settings, then System, then Windows Update. Click Check for updates. Windows will tell you whether you're current or whether updates are waiting to read and install.

If updates are available, Windows will usually read them automatically and ask you to restart your computer. Don't ignore this — restarting completes the installation and closes security gaps that hackers could use. If you keep putting off the restart, your computer becomes more vulnerable over time.

What to do if you're running an old version of Windows

If the About screen shows Windows 7, Windows 8, or Windows 8.1, your computer is no longer receiving security updates from Microsoft. This doesn't mean your computer will stop working tomorrow, but it does mean that new viruses and security problems won't be patched. Over time, this becomes a real risk — especially if you use your computer for banking, email, or shopping.

The safest path forward is to upgrade to Windows 10 or Windows 11. If your computer is very old, it might not meet the hardware requirements for Windows 11 (which requires a specific processor and at least 4 GB of RAM). In that case, Windows 10 is still receiving updates and will continue to for several more years. You can check whether your computer can run Windows 11 by going to Settings > System > About and looking for a line that says "System type" — if it says "64-bit", you're more likely to be compatible.

Using the command line if Settings won't open

If your Settings app is frozen or won't respond, you can find your Windows version through the command line. Press the Windows key and type "cmd", then right-click Command Prompt and select Run as administrator. Type systeminfo and press Enter. The command will print out a long list of information about your computer, including "OS Name" (which shows your Windows version) and "OS Version" (which shows the build number).

This method is slower than using Settings, but it works even when the graphical interface is sluggish or unresponsive. Write down the OS Name and OS Version lines so you have them handy if you need to search for help or contact support.

Frequently Asked Questions

Is Windows 10 still getting updates?

Yes, but not forever. Windows 10 receives updates through October 2025. After that date, Microsoft will stop releasing security patches. If you're running Windows 10 now, you have time to plan an upgrade to Windows 11, but don't wait until the last month.

Can I upgrade from Windows 10 to Windows 11 for free?

If your computer meets the hardware requirements (64-bit processor, 4 GB RAM, 64 GB storage, and a compatible motherboard), you can upgrade for free. Go to Settings > System > Windows Update and click "Check for updates" — Windows will offer the upgrade if your computer qualifies. If it doesn't may have access to, you'll need to buy a Windows 11 license or replace your computer.

What if the About screen shows a version number I don't recognize?

Version numbers change frequently as Microsoft releases updates. You don't need to understand the exact number — what matters is whether you're on Windows 10, Windows 11, or an older version. If you're concerned about whether you're current, go to Windows Update and click "Check for updates". If nothing is available, you're up to date.

Does knowing my Windows version help with computer speed?

Indirectly, yes. Older versions of Windows sometimes run slower on modern hardware because they weren't designed for it. Newer versions are often optimized for current processors and RAM. If you're running Windows 7 or 8 on a newer computer, upgrading to Windows 10 or 11 might improve performance, though the biggest speed boost usually comes from having enough free disk space and RAM.
