The fastest way to check your Windows version

Open the Settings app by pressing Windows key + I on your keyboard. Go to System in the left menu, then 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 or checking whether you have the latest updates.

If Settings doesn't open or feels slow, you can also right-click the This PC or My Computer icon on your desktop, select Properties, and find the same information in the window that appears. Both methods take less than 30 seconds.

Key Takeaways

  • Press Windows key + I, go to System, then About to see 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 This PC and selecting Properties shows the same information if Settings is not responding.
  • Knowing your version matters when installing drivers, checking compatibility with software, or following troubleshooting steps that differ between Windows versions.

Why you need to know your Windows version

Different versions of Windows handle updates, driver installation, and hardware compatibility differently. If you're installing a printer driver or graphics card software, the manufacturer often asks which Windows version you have so they can give you the right file. Running an older version like Windows 7 or Windows 8 also affects which security patches and software updates are still available — Microsoft stopped supporting Windows 7 in January 2020, meaning no new security fixes are released for it.

When you search for help with a computer problem online, the solution often depends on your version. A fix that works in Windows 11 might not work in Windows 10, and instructions for Windows 10 can be completely different from Windows 7. Knowing your exact version saves you from following steps that don't explore to your machine.

Understanding Windows edition versus version number

The Edition is the product line: Windows 11 Home, Windows 11 Pro, Windows 10 Home, Windows 10 Pro, and so on. Home is the standard version most people buy with a new computer. Pro includes extra features like Remote Desktop and BitLocker encryption, and costs more. Enterprise and Education editions exist for businesses and schools.

The Version number (like 22H2 or 21H2) refers to the update cycle. Microsoft releases major updates to Windows twice a year, and each one gets a version number. The build number is even more specific — it's the exact snapshot of code you have installed. You don't usually need to memorize these numbers, but they're useful when you're reporting a bug or checking whether you have the latest security patches.

Checking for Windows updates after you know your version

Once you know your version, you can check whether you're fully up to date. In Settings, go to System, then Windows Update, and click Check for updates. Windows will read and install any patches released since your current version. This is one of the most important steps for keeping your computer running smoothly — updates fix security holes, improve performance, and patch bugs that slow down your system.

If Windows says you're up to date but you want to confirm, write down the version number from the About page, then search online for the latest version number for your edition. If they match, you're current. If they don't, click Check for updates again — sometimes it takes a few tries or a restart before Windows finds the latest release.

What to do if you have an old Windows version

If you're running Windows 7, Windows 8, or Windows 8.1, Microsoft no longer releases security updates for those versions. That means new viruses and hacking methods are not being patched, and your computer becomes less find the longer you use it. The practical solution is to upgrade to Windows 10 or Windows 11.

Windows 10 is still receiving updates and will continue to do so until October 2025. Windows 11 is the current version and will receive updates for many years. You can usually upgrade from an older version to Windows 10 or 11 for free or at a reduced cost, though the process takes an hour or two and requires a restart. If your computer is very old, it may not meet the hardware requirements for Windows 11 — in that case, Windows 10 is the next best option.

Finding your version on a computer that won't start normally

If Windows won't boot into the normal desktop, you can still find your version from the login screen or recovery environment. On the login screen, look for a small text line in the bottom right corner that sometimes shows the Windows version. If that's not visible, restart your computer and press F8 or Shift + F8 repeatedly as it boots — this opens the Advanced Startup Options menu, where you can select Troubleshoot, then Reset this PC. The recovery environment will show your Windows version before you make any changes.

If your computer won't respond at all, you can also check the version from another computer by connecting your hard drive as an external drive, or by using a Windows installation USB to boot into recovery mode. These steps are more involved, but they work when the normal Settings method is not available.

Frequently Asked Questions

What's the difference between Windows 10 and Windows 11?

Windows 11 has a redesigned interface with a centered taskbar and Start menu, improved performance on newer hardware, and better integration with Android phones. Windows 10 still works fine and receives updates through October 2025. Windows 11 requires newer hardware — specifically a compatible processor and TPM 2.0 chip — so not all older computers can upgrade.

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

Yes, if your computer meets the hardware requirements. Go to Settings, System, Windows Update, and click Check for updates. If your machine qualifies, you'll see an option to upgrade. If you don't see it, your processor or other hardware doesn't meet Windows 11's minimum requirements.

Does knowing my Windows version help with slow performance?

Yes. Outdated versions often run slower because they lack performance improvements in newer updates. Checking your version and updating to the latest build can noticeably improve speed. It also helps you follow troubleshooting steps specific to your version, since performance fixes differ between Windows 10 and Windows 11.

What if the version number in Settings looks wrong or outdated?

Go to Windows Update and click Check for updates, then restart your computer. Sometimes the display doesn't refresh when ready. If you still see an old version after a restart, click Check for updates again — the update may be pending installation.
