The quickest way to check your Windows version

Open the Settings app by pressing the Windows key and typing "settings", then select the Settings app from the results. Go to System in the left sidebar, scroll down, and click About. Look for the line that says Edition — this shows whether you have Windows 11, Windows 10, or an older version. The Version line below it shows the specific build number, which tells you how current your installation is.

If you prefer not to open Settings, you can also press Windows key + R to open the Run dialog, type winver, and press Enter. A window will pop up showing your edition and version number immediately.

Key Takeaways

  • Settings > System > About shows your Windows edition (like Windows 11 Home) and version number in one place.
  • The Run dialog shortcut winver opens the same information faster if you prefer keyboard navigation.
  • Your edition tells you which Windows product you own; your version number tells you how recent your updates are.
  • Windows 10 and Windows 11 look slightly different in Settings, but both show the same information in the About section.

Understanding Windows editions versus versions

The edition is the product you bought or came with your computer — Windows 11 Home, Windows 11 Pro, Windows 10 Home, or Windows 10 Enterprise. This determines which features you can use. The version is a number like 23H2 or 22H2, which represents how many updates your system has received. Two computers running Windows 11 Home can have different version numbers if one has been updated more recently than the other.

Your version number matters because older versions stop receiving security updates after a certain date. Microsoft typically supports each version for about 18 months, so checking your version helps you know whether you need to run Windows Update to stay protected.

Using the System Information window for more detail

If you need more technical details about your system, press Windows key + R, type msinfo32, and press Enter. The System Information window shows your edition, version, and build number, plus information about your processor, RAM, and system type (32-bit or 64-bit). Most people do not need this level of detail, but it is useful if you are troubleshooting a problem or checking whether your computer meets requirements for a specific program.

The build number in System Information is the most specific identifier for your Windows installation. If you contact Microsoft support or a technician, they may ask for your build number to pinpoint exactly which version you are running.

Checking your version on older Windows systems

If you are running Windows 7, Windows 8, or Windows 8.1, the process is slightly different. Right-click This PC or My Computer on your desktop, select Properties, and look for the Windows edition near the top of the window. You can also press Windows key + Pause/Break to open the same Properties window directly.

Windows 7 and Windows 8 do not receive updates anymore, so if you are using either of these, you should consider upgrading to Windows 10 or Windows 11 for security reasons. Microsoft stopped supporting Windows 7 in January 2020 and Windows 8 in January 2016, meaning no new security patches are released for these versions.

What to do if you need to update Windows

Once you know your version, you can check whether updates are available. Open Settings, go to System, and click Windows Update on the left sidebar. Click Check for updates and Windows will search for any new versions or patches. If updates are available, you will see them listed with an option to download and install.

Updates usually install automatically on Windows 10 and Windows 11, but you can also install them manually from this screen. Your computer may need to restart after installing updates, so plan accordingly if you are in the middle of work.

Finding your Windows product key

The Settings > System > About section shows your edition but not your product key. If you need to find your product key — for example, to reinstall Windows on the same computer — you can use a command-line tool. Press Windows key + R, type powershell, right-click the result, and select Run as administrator. Paste this command and press Enter: wmic os get serialnumber. This displays your product key in the window.

Keep your product key in a safe place. If you lose it and need to reinstall Windows, you may have difficulty proving you own a license. Some computers have the key printed on a sticker on the back or bottom of the machine.

Frequently Asked Questions

Is my Windows version the same as my Windows edition?

No. Your edition is the product type (Home, Pro, Enterprise), and your version is the update level (23H2, 22H2). You need both pieces of information to fully describe what you are running. For example, "Windows 11 Pro version 23H2" tells someone exactly what you have.

Why does my version number look like a date?

Microsoft changed its naming system starting with Windows 10 version 21H2. The letters and numbers represent the year and half-year of release — 23H2 means the second half of 2023. Older versions used different numbering, like 1909 or 2004, which also encoded the release date.

What should I do if my version is very old?

Run Windows Update immediately. Go to Settings > System > Windows Update and click Check for updates. If your version is more than a year old, you may be missing important security patches. Windows will download and install all available updates, which may require a restart.

Can I downgrade to an older version of Windows?

You can roll back to a previous version within a limited window — usually 10 days after a major update. Go to Settings > System > Recovery and look for the Go back option. After that window closes, downgrading requires reinstalling Windows from scratch, which erases your files.

Does knowing my Windows version help with software compatibility?

Sometimes. Some older programs require Windows 7 or 8 and will not run on Windows 10 or 11. Some newer programs require Windows 10 version 1909 or later. Checking your version before installing software helps you avoid compatibility problems, especially with specialized or older applications.
