Difference between version, edition, and build number

These terms get mixed up all the time, but they’re not the same thing:

• Version: The major release like Windows 10 or Windows 11
• Edition: Home, Pro, Enterprise – these determine what features you get
• Build number: This is the specific update package installed (like 19044.1826)

If you’re curious about the different Windows 11 versions and their release dates, Microsoft keeps an up-to-date list you can check anytime.

The Easiest Way to Check Windows Version — Use the “Winver” Command

The winver command is probably the quickest way to check your Windows version:

1. Press the Windows key + R on your keyboard.
   This will open the Run dialog box. Don’t worry — it’s just a small pop-up.
2. In the box, type winver and hit Enter.
3. A little window will pop up with your Windows version and OS build number.

For example, it might say something like:
Windows 11 Pro, Version 23H2 (OS Build 22631.5335)

Here’s a quick breakdown:

• Version 23H2 – This tells you the major release of Windows you’re using.
• OS Build 22631.5335– This is the detailed build number, which shows minor updates and patches.

Another Way — Using System Settings to Check Windows Version

Want a quick way to check your Windows version? The Settings app has got you covered.

1. Click the Start button and select Settings (gear icon).
   Or press Windows key + I to open Settings directly.
2. In the Settings window, click on System.
3. Scroll down and click on About (you’ll find this on the left or at the bottom, depending on your Windows version).
4. Under Windows specifications, you’ll see:
5. Edition (like Windows 11 Pro or Home)
6. Version (like 23H2)
7. Installed on date
8. OS build (something like 22631.5335)

The version number tells you which major update you have, while the build number reveals the specific minor update installed on your PC.

Optional Method — Using the Windows Command Prompt

For those who prefer typing over clicking, the Command Prompt is your best friend. To check your Windows version, simply:

1. Click Start, type cmd, and press Enter.
2. In the black Command Prompt window, type: systeminfo | findstr /B /C:”OS Name” /C:”OS Version”
3. Press Enter and boom! You’ll see your Windows version and build in plain text.

It might look like this:

• OS Name: Microsoft Windows 11 Pro
• OS Version: 10.0.22631 N/A Build 22631

This filters out just the OS information from a larger data set. Super handy when you need to quickly verify which Windows version you’re running.
