How to check what Windows 10 build you are on in two easy steps

Many users of Windows 10 have a solid idea of which build they are on. In fact, most consumers likely do not know, and that is an OK thing. Windows 10 should be transparent, and users should not have to know the exact build of the OS they are running.

Windows Insiders, however, are a different breed. You, folks, like to keep tabs on every release and sometimes, just sometimes, you may have forgotten which build you are on. Alternatively, sometimes things update but you do not know what changed.

Luckily, you can discover which build you are for Windows 10 in two easy steps. Let’s go!

Check Windows 10 Build Version

1. Win + R

Open up the run command with the Win + R key combo

2. Launch winver

Simply type in winver into the run command text box and hit OK

That is it. You should now see a dialog screen revealing the OS build and registration information.

Another way instead of using Win + R is to (1) type in winver into the Cortana search box and (2) select the first surfaced result.

Note, if you are a Windows 10 Insider, you will likely have an expiration date for the build. No need to fret over this as you can always stop getting insider builds and your OS will revert to a non-expiring edition. In theory, Microsoft is going to keep updating Windows 10 through the Insider Program and this date will continually get pushed back.

Also, as an interesting observation, I noticed my OS shows Windows 8 at the top. Microsoft’s Gabriel Aul notes that this is just a bug and most users will see Windows 10 or even just Windows at the top.

Finally, I am sure many of you have noticed the return of the ‘test mode’ watermark on the 10525 desktop. For Insiders, this is also the easiest way to check your build number 😉

Anyway, hopefully, you now know how to quickly check your build number!

What Version of Windows Do I Have?

How to tell which version of Windows is installed on your computer

Do you know what version of Windows you have? While you usually don’t need to know the exact version number for whatever Windows version you have installed, general information about the operating system version you’re running is very important.

Why You Should Know Which Version of Windows You Have

Everyone should know three things about the Windows version they have installed: the major version of Windows, like 10, 8, 7, etc.; the edition of that Windows version, like Pro, Ultimate, etc.; and whether that Windows version is 64-bit or 32-bit.

If you don’t know what version of Windows you have, you won’t know what software you can install, which device driver to choose for an update—you may not even know which directions to follow for help with something!

Keep in mind that the taskbar icons and Start menu entries in these images might not be exactly what you have on your computer. However, the structure and general appearance of each Start button will be the same, so long as you don’t have a custom Start menu installed.

Windows 10

You have Windows 10 if you see a Start menu like this when you select the Start button from the desktop. If you right-click the Start menu, you’ll see the Power User Menu.

The Windows 10 edition you have installed, as well as the system type (64-bit or 32-bit), can all be found listed in the System applet in Control Panel.

Windows 10 is the name given to Windows version 10.0 and is the latest version of Windows. If you just got a new computer, there’s a 99 percent chance you have Windows 10 installed. (Maybe closer to 99.9 percent!)

The Windows version number for Windows 10 is 10.0.

Windows 8 or 8.1

You have Windows 8.1 if you see a Start button on the bottom-left of the desktop and selecting it takes you to the Start menu.

You have Windows 8 if you don’t see a Start button at all on the desktop.

The Power User Menu when right-clicking the Start button in Windows 10, is also available in Windows 8.1 (and the same is true for right-clicking the corner of the screen in Windows 8).

The edition of Windows 8 or 8.1 you’re using, as well as information on whether or not that version of Windows 8 is 32-bit or 64-bit, is all found in Control Panel from the System applet.

If you’re not sure if you’re running Windows 8.1 or Windows 8, you’ll also see that information listed in the System applet.

Windows 8.1 is the name given to Windows version 6.3, and Windows 8 is Windows version 6.2.

Windows 7

You have Windows 7 if you see a Start menu that looks like this when you select the Start button.

The Windows 7 & Windows Vista (below) Start buttons and Start menus look very similar. The Windows 7 Start button, however, fits completely inside the taskbar, unlike the one for Windows Vista.

Information on which Windows 7 edition you have, as well as whether it’s 64-bit or 32-bit, is all available in the Control Panel in the System applet.

Windows 7 is the name given to Windows version 6.1.

Windows Vista

You have Windows Vista if, after clicking the Start button, you see a menu that looks a lot like this.

As you read in the Windows 7 section above, both versions of Windows have similar Start buttons and menus. One way to tell them apart is to look at the button itself—the one in Windows Vista, unlike in Windows 7, extends above and below the taskbar.

Information on the Windows Vista edition you’re using, as well as whether your version of Windows Vista is 32-bit or 64-bit, are all available from the System applet, which you can find in Control Panel.

Windows Vista is the name given to Windows version 6.0.

Windows XP

You have Windows XP if the Start button includes both a Windows logo as well as the word start. In newer versions of Windows, as you can see above, this button is just a button (without text).

Another way the Windows XP Start button is unique when compared with newer versions of Windows is that it’s horizontal with a curved right edge. The others, as seen above, are either a circle or square.

Like other versions of Windows, you can find your Windows XP edition and architecture type from the System applet in Control Panel.

Windows XP is the name given to Windows version 5.1.

Unlike with newer versions of Windows, the 64-bit version of Windows XP was given its own version number: Windows version 5.2.

How to Find the Windows Version With a Command

While the images and information above is the best way to determine the version of Windows you’re running, it’s not the only way. There’s also a command you can run on your computer that will display an About Windows screen with the Windows version included.

It’s really easy to do this regardless of the version of Windows you’re running; the steps are identical.

Just invoke the Run dialog box with the Win+R keyboard shortcut (hold down the Windows key and then press R once). Once that box shows up, enter winver (it stands for Windows version).
