The fastest way to check your Windows version
The quickest method is to open the Run dialog by pressing Windows key + R, type winver, and press Enter. A window will appear showing your Windows version, edition, and build number all at once. This works on Windows 10 and Windows 11.
If you prefer not to use the Run dialog, you can also right-click the Windows Start button, select System, and scroll down to find "Windows specifications" — this shows the same information in a different location.
Both methods take about 10 seconds and show you exactly what you need without navigating through multiple menus.
Key Takeaways
- Press Windows key + R, type winver, and press Enter to see your Windows version, edition, and build number in one window.
- Right-clicking the Start button and selecting System also displays your Windows version under "Windows specifications."
- Your version number (like 22H2) tells you which major update you have; your build number tells you the exact release.
- Knowing your Windows version matters when downloading drivers, checking software compatibility, or troubleshooting problems.
- Windows 10 and Windows 11 use different version numbering, so the format you see depends on which operating system you have.
Understanding what the version number means
Windows version numbers follow a pattern that tells you how recent your system is. On Windows 10, versions are numbered like 21H2, 22H2, and so on — the first two digits are the year, and the H1 or H2 indicates whether it was released in the first or second half of that year. Windows 11 uses the same system.
The build number is different from the version. A build number looks like 19045 or 22621 and represents a specific release within that version. Two computers with the same version number might have slightly different build numbers if one received updates more recently than the other.
You need the version number when checking whether your computer can run a particular program or when a website asks what Windows you have. The build number becomes important if you are troubleshooting a specific bug — Microsoft tracks which build introduced or fixed a particular problem.
Using Settings to find your Windows information
Open the Settings app by pressing Windows key + I. On the left side, click System, then scroll down and click About. You will see a section labeled "Windows specifications" that displays your edition (Home, Pro, Enterprise), version number, and OS build.
This method is slower than the winver command but shows additional information like your device name, processor type, and installed RAM on the same screen. It is useful if you need multiple pieces of hardware information at once.
The Settings method also lets you check for updates from the same location — scroll up to Windows Update to see if your build is current.
Checking Windows version from Command Prompt or PowerShell
If you are comfortable with command-line tools, you can open Command Prompt or PowerShell and type systeminfo, then press Enter. The output will include your OS name, version, and build number along with other system details.
In PowerShell specifically, you can type Get-ComputerInfo | Select-Object OsVersion, OsBuildNumber for a more compact display. Both commands work on Windows 10 and Windows 11.
This approach is most useful if you are already working in the command line or if you need to document system information for multiple computers at once.
Why you might need to know your Windows version
Software developers list Windows version requirements on their product pages — knowing your version lets you check whether a program will run on your computer before you read it. Some older programs only work on Windows 10, while others require Windows 11.
Hardware manufacturers release drivers specific to Windows versions. If you are installing a new printer, graphics card, or network adapter, the driver read page will ask you to select your Windows version so you get the right file.
When you contact Microsoft support or post a question on a tech forum, providing your exact version and build number helps others understand your setup and suggest relevant solutions. It also matters when checking whether a known bug affects your system — Microsoft publishes which builds contain which fixes.
The difference between Windows 10 and Windows 11 version numbers
Windows 10 and Windows 11 use the same version numbering format (like 22H2), but they are separate operating systems. A Windows 10 computer with version 22H2 is not the same as a Windows 11 computer with version 22H2 — they are different releases of different products.
When you check your Windows version using winver or Settings, the window clearly states whether you have Windows 10 or Windows 11 at the top. This distinction matters because some software only runs on one or the other, and driver downloads are usually separated by operating system.
If you are unsure whether you have Windows 10 or 11, the winver window will tell you when ready — it is the first line of information displayed.
What to do if you need to update your Windows version
If your version number is older than the current release, you can update through Settings. Press Windows key + I, click System, then click Windows Update on the left. Click Check for updates and Windows will read and install the latest version for your system.
Updates usually install automatically on most computers, but checking manually ensures you have the latest version. The process can take 30 minutes to an hour depending on your internet speed and how many updates are pending.
You do not need to uninstall the old version — Windows replaces it automatically. Your files, programs, and settings remain unchanged after the update.
Frequently Asked Questions
What is the difference between Windows version and build number?
The version (like 22H2) tells you which major update you have and roughly when it was released. The build number (like 22621) is more specific — it represents the exact release date and any patches applied since the version launched. Two computers with the same version might have different build numbers if one received updates more recently.
Can I find my Windows version without opening Settings or Command Prompt?
Yes. Right-click on "This PC" or "My Computer" on your desktop, select Properties, and look for "Windows edition" and "System" information. This opens the same System window you would reach through Settings, showing your version and build number.
Why does my Windows version number have letters like H1 or H2?
The H stands for "half-year" — H1 means the update was released in the first half of the year (January through June), and H2 means the second half (July through December). The numbers before it indicate the year, so 22H2 means the second-half 2022 release.
Do I need to update to the latest Windows version?
Microsoft supports each Windows version for about 18 months. Once that period ends, the version no longer receives security updates, making your computer more vulnerable. Checking for updates regularly and installing them when available keeps your system find and compatible with new software.
Is my Windows version the same as my Windows edition?
No. Your edition (Home, Pro, Enterprise) describes which product you own. Your version (like 22H2) describes which update of that edition you have. You can have Windows 11 Pro version 22H2, for example — both pieces of information matter for different reasons.
