How to Check Your Windows Version in Windows 10

Knowing exactly which version of Windows 10 you're running matters more than most people realize. Software compatibility, security patch eligibility, driver support, and upgrade paths all depend on it. Windows 10 isn't a single static operating system — it's a platform that Microsoft has updated dozens of times since its 2015 launch, and each update carries its own version number, build number, and feature set.

Here's everything you need to know about finding that information and understanding what it actually means.

Why Your Windows 10 Version Number Matters

Microsoft releases feature updates to Windows 10 roughly once or twice a year. Each one gets a version number in the format YYMM — for example, version 22H2 means the second half of 2022. Underneath that sits a more granular build number, which tracks smaller cumulative updates and security patches.

These aren't just cosmetic labels. Applications, enterprise management tools, and even some hardware drivers check your version or build before they'll install or run correctly. If you're troubleshooting a compatibility issue, filing a support ticket, or checking whether your PC is still receiving security updates, your version number is the first thing you need.

Method 1: Settings App (The Easiest Way) ⚙️

This is the most straightforward path for everyday users.

1. Press Windows key + I to open Settings
2. Click System
3. Scroll down and select About
4. Look under the Windows specifications section

You'll see four fields here:

The Edition and Version fields answer most questions. The OS build is what you'll need for detailed troubleshooting or support.

Method 2: winver Command (Fast and Reliable)

This method works from anywhere in Windows and takes about five seconds.

1. Press Windows key + R to open the Run dialog
2. Type winver and press Enter

A small window appears titled About Windows. It displays your Windows 10 version number and full OS build in a clean, easy-to-read format. This is the method IT professionals and support teams typically use because it's fast and unambiguous.

Method 3: System Information Tool

For a more detailed picture — useful when checking hardware alongside software details:

1. Press Windows key + R
2. Type msinfo32 and press Enter

The System Information window opens. Under System Summary, look for:

• OS Name — confirms it's Windows 10 and the edition
• Version — the full build string
• OS Build Type — multiprocessor vs. uniprocessor (rarely relevant for home users)

This tool is particularly useful when you need to copy or share full system specifications, since everything is in one place.

Method 4: Command Prompt or PowerShell

If you're comfortable with the command line, two commands return version information instantly.

In Command Prompt:

winver 

(Same result as Method 2, launched from the command line.)

Or for a text-based output you can copy:

systeminfo | findstr /B /C:"OS Name" /C:"OS Version" 

In PowerShell:

Get-ComputerInfo | Select-Object WindowsProductName, WindowsVersion, OsBuildNumber 

PowerShell's output is especially useful in enterprise or scripting environments where you need to capture or log version data programmatically.

Understanding the Version Number You Find 🔍

Once you have your version number, here's what the format tells you:

• 21H1 = First half of 2021
• 21H2 = Second half of 2021
• 22H2 = Second half of 2022 (the final feature update for Windows 10)

Each version has an end-of-service date — after that date, Microsoft stops issuing security updates for that version. If you're running an older version that's past its end-of-service date, your system isn't receiving patches, even if Windows 10 itself still technically works.

The build number after the decimal point (e.g., 19045.4651) tracks cumulative updates. A higher number means more recent patches have been applied within the same feature version.

Edition Differences Also Matter

The Edition field in Settings isn't just branding. Windows 10 Home, Pro, Enterprise, and Education have meaningfully different feature sets:

Some software — particularly business and security tools — requires Pro or Enterprise. If you're troubleshooting a missing feature, checking your edition is the logical first step.

What the Version Information Doesn't Tell You Automatically

Your version number confirms what Microsoft has shipped to your device. It doesn't tell you whether that version is the latest available for your hardware, whether your specific device is still eligible for updates, or whether a pending update is waiting in the queue. Those answers require checking Windows Update separately under Settings > Update & Security.

Hardware compatibility with newer versions also varies. The PC Health Check tool (available from Microsoft's website) is the standard way to assess whether a specific machine meets the requirements for moving beyond Windows 10 entirely — but that's a separate question from simply knowing what version you're currently on.

Your version number is the starting point. What you do with it depends entirely on why you needed it in the first place — and that's where your own situation becomes the deciding factor. 🖥️
