Check your Windows version in Settings
The fastest way to find your Windows version is through the Settings app. Open Settings by pressing the Windows key and the letter I together, or by clicking the Start menu and selecting Settings. Once Settings opens, click on System in the left sidebar, then scroll down and click About.
On the About page, look for the line that says Edition. This tells you whether you have Windows 11, Windows 10, or an older version. Below that, you will see Version, which shows the specific update number — for example, version 23H2 or 22H2. You will also see OS Build, a longer number that identifies the exact build your computer is running.
Write down or take a screenshot of these three pieces of information if you need them for troubleshooting or to check whether your computer can run a particular program. Different software sometimes requires a minimum Windows version or build number.
Key Takeaways
- Open Settings, go to System, then About to see your Windows Edition, Version, and OS Build in one place.
- The Edition tells you Windows 10 or Windows 11; the Version number shows which update you have installed.
- You can also use the Run dialog (Windows key + R, then type winver) to open a dedicated window showing the same information.
- Knowing your OS Build number helps when you contact support or need to check whether your computer meets a program's requirements.
Use the Run dialog for a quick view
If you prefer a faster method, use the Run dialog. Press the Windows key and the letter R at the same time. A small box will appear. Type winver and press Enter.
A window titled "About Windows" will open and display your Windows Edition, Version, OS Build, and System information all at once. This method takes fewer clicks and opens a dedicated window that shows nothing else, so the information is straightforward to read. Close the window when you are done.
Find your version through System Information
System Information is a more detailed tool that shows your Windows version along with hardware details. Press the Windows key and the letter R together, type msinfo32, and press Enter.
The System Information window will open. Look for the line labeled OS Name — this shows your full Windows version, such as "Microsoft Windows 11 Pro". Below that, Version shows your update number, and OS Build shows the build number. This tool is most useful if you need to share detailed system information with technical support or if you want to see your processor, RAM, and other hardware specs at the same time.
Check Windows version from the command line
If you are comfortable using the command line, you can find your version there too. Press the Windows key and the letter R, type cmd, and press Enter to open Command Prompt.
Type systeminfo and press Enter. The command will display a list of system details, including OS Name and OS Version. Scroll up if needed to find these lines. This method is less common for everyday use, but it is useful if you are troubleshooting with someone remotely or if you need to document your system information in a text file.
Understand what each version number means
Windows comes in different editions, and knowing which one you have matters for compatibility. Windows 11 Home is the standard version for most personal computers. Windows 11 Pro includes extra features like remote desktop and encryption tools. Windows 10 is an older version that many computers still run; Microsoft stopped releasing major updates for it in October 2025, though security updates continue.
The Version number (like 23H2 or 22H2) tells you which update you have. The "H" stands for half-year, so 23H2 means the second update released in 2023. Your computer should install these updates automatically, but if you have not restarted recently, you might be running an older version.
The OS Build number is the most specific identifier. If you contact Microsoft support or a software company about a problem, they may ask for your build number because it pinpoints exactly which version you are running. You do not need to memorize it, but keeping a note of it can speed up troubleshooting.
Why knowing your version matters
Your Windows version affects which programs will run on your computer and which security updates you receive. Some software requires Windows 11 or a specific build number to function. Older programs may not work on the newest Windows versions without compatibility adjustments.
If your computer is running an older build, checking for updates is a good next step. Open Settings, go to System, then Windows Update, and click Check for updates. Installing the latest updates keeps your computer find and can fix bugs or improve performance. After updates install, you may need to restart your computer before the new version number appears in Settings.
Frequently Asked Questions
What is the difference between Windows 10 and Windows 11?
Windows 11 is the newer operating system with a redesigned interface, better performance on newer hardware, and additional security features. Windows 10 is older but still receives security updates. If your computer is several years old, it may not meet Windows 11's hardware requirements, even if you wanted to upgrade.
Do I need to update if I see an older Version number?
Yes, you should install updates when they become available. Updates include security patches that protect your computer from threats. Go to Settings > System > Windows Update and click Check for updates. Your computer will read and install them automatically, though you may need to restart.
What if my computer says Windows 10 but I thought I had Windows 11?
Your computer is running Windows 10. If you want Windows 11, you can upgrade through Settings > System > Windows Update, but your hardware must meet Windows 11's requirements — mainly a compatible processor and TPM 2.0 chip. Check Microsoft's official requirements before attempting an upgrade.
Why does my OS Build number keep changing?
Your OS Build number changes when you install Windows updates. Each update includes a new build number. This is normal and means your computer is receiving security patches and bug fixes. You do not need to do anything — updates install automatically in the background.
Can I find my Windows version on the login screen?
No, the login screen does not display version information. You must log in first, then use Settings, the Run dialog, or System Information to check your version. If you cannot log in, you can restart your computer and check the version after logging in.
