The quickest way to check your Windows version

Open the Settings app by pressing the Windows key and typing "Settings", then click the result. 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. Below that, "Version" shows the specific update number, and "OS Build" shows the exact build you're running.

If Settings doesn't open or feels slow, you can also press Windows key + R, type winver, and press Enter. A window will pop up showing your edition, version, and build number in one place.

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 place Windows stores your version information and is the same on every Windows computer.
  • The "Edition" line tells you Windows 10 or Windows 11; the "Version" line tells you which update; the "OS Build" line tells you the exact build number.
  • If you need to share this information with tech support or check compatibility before installing something, the winver command gets you there fastest.
  • Your version number changes when you install a major update, but your edition (Home, Pro, Enterprise) usually stays the same unless you upgrade Windows itself.

Why your version number matters

Your Windows version determines which security updates you receive, which features are available to you, and whether new software will run on your machine. Older versions like Windows 7 or Windows 8 no longer receive security patches, which means vulnerabilities stay open. Knowing your version tells you whether you're on a version that still gets updates.

Version numbers also matter when you're troubleshooting. If you contact tech support or post in a forum, the first thing they'll ask is what version you're running — the same problem might have different solutions depending on whether you're on Windows 10 or Windows 11, or whether you're on an older update of either one.

Understanding the difference between Edition and Version

Edition refers to the tier of Windows you bought: Home, Pro, Enterprise, or Education. These are different products with different features. Windows 10 Home and Windows 10 Pro are both Windows 10, but Pro includes features like Group Policy and remote desktop that Home doesn't have. Your edition almost never changes unless you pay to upgrade it.

Version refers to the update cycle. Windows 10 and Windows 11 both release major updates roughly twice a year. Version 22H2 means the 2022 H2 (second half) update. Version numbers change automatically when you install updates; you don't choose them. Knowing your version tells you how current your security patches are.

What the OS Build number tells you

The OS Build is the most specific identifier Windows has. It's a number like 19045.3693 that changes with every patch Tuesday update. If you're troubleshooting a specific bug or checking whether a particular security patch has been installed, the build number is what you need.

You don't usually need to memorize your build number, but it's useful to have when you're reporting a problem to Microsoft or checking the Windows release notes to see what changed in your latest update. You can search your build number on the Microsoft website to find the exact date it was released and what it fixed.

Checking your version on older Windows systems

If you're running Windows 7, Windows 8, or Windows 8.1, the steps are slightly different. Right-click This PC or My Computer on your desktop, select Properties, and look for "System" information. You'll see your edition and service pack level, though these older versions don't use the "Version" and "Build" labels the same way newer Windows does.

If you're on an older version, you should know that Windows 7 stopped receiving updates in January 2020, and Windows 8 and 8.1 stopped in January 2023. Running an unsupported version means security vulnerabilities won't be patched. Checking your version is the first step toward deciding whether you need to upgrade to Windows 10 or Windows 11.

Using the command line to check your version

If you prefer the command line, you have a few options. Press Windows key + R, type cmd, and press Enter to open Command Prompt. Then type systeminfo and press Enter. Scroll up to find "OS Name" (your edition), "OS Version" (your version number), and "System Boot Time" and other details.

Alternatively, in Command Prompt type wmic os get caption,version,buildnumber and press Enter. This shows the same information in a more compact format. These methods are useful if Settings isn't responding or if you're troubleshooting a system that won't start normally.

What to do after you know your version

Once you know your version, you can check whether you're up to date. Go to Settings > System > Windows Update and click Check for updates. Windows will tell you whether your system is current or whether updates are waiting to install. If updates are available, Windows will read them automatically and prompt you to restart.

You can also use your version number to check the Windows release notes on Microsoft's website. Search for your version number and you'll find a list of what was fixed, what features were added, and any known issues. This is especially useful if you just updated and something isn't working the way you expected.

Frequently Asked Questions

How often does my Windows version number change?

Microsoft releases major updates twice a year, usually in spring and fall. Your version number updates when you install one of these. Security patches install monthly on Patch Tuesday but don't change your version number — they change your build number instead. You can set Windows to install updates automatically or check manually whenever you want.

Is Windows 10 and Windows 11 the same version?

No. Windows 10 and Windows 11 are different editions. Both receive regular updates and have version numbers, but they're separate products. Windows 10 will stop receiving updates in October 2025, so if you're on Windows 10, you'll eventually need to upgrade to Windows 11 to keep getting security patches.

Why does my version number look different from my friend's?

If you and your friend both have Windows 11 but different version numbers, one of you installed updates more recently than the other. Windows rolls out updates gradually, so not everyone gets them on the same day. Both versions are supported as long as they're current, but you should install updates when they're available to stay find.

Can I change my Windows version or edition?

You can't choose which version you get — updates install automatically or when you check for them. You can upgrade your edition (from Home to Pro, for example) by paying for an upgrade key, but that's different from a version update. Downgrading to an older version is possible but requires reinstalling Windows and is not recommended.

What if my version number is really old?

If your version number is more than a year old, you likely have updates waiting. Go to Settings > System > Windows Update and click Check for updates. Windows may need to restart several times to install all pending updates. If updates won't install, your system might have a hardware issue or a corrupted update file — in that case, contact Microsoft support or a local technician.
