How to Find the Windows version, build and edition from ISO or DVD

Windows 10 ISO files downloaded from Microsoft will have descriptive names, such as en_windows_10_pro_10586_x64_dvd.iso and en_windows_10_pro_14393_x86_dvd.iso , depending upon the variant you downloaded. The file name depicts the language, version, build edition and the bitness of the Operating System contained in the ISO.

Let’s assume you have a copy of the Windows ISO with a generic name such as windows_10.iso (which doesn’t make any sense) obtained from a friend. To find the Windows version, build and edition from an ISO file or Windows Setup DVD, you can use the DISM tool.

Find Windows version, build, edition from ISO file

To find the Windows version, build and edition from an ISO file or DVD, use these steps:

1. Mount the ISO file by double clicking on it. By default, Mount will be the default action for ISO files. If not, right-click on the file and choose “Mount” in the context menu.
2. Double-click the drive letter of the mounted drive.
3. Double-click the Sources folder.
4. Sort folder contents by Name, and look for a file named install.wim . If install.wim is missing, then you’ll have install.esd .

Install.esd located in the Sources folder.

Open an elevated Command Prompt window, and then type the following command:

In the ISO file, if you have install.esd instead of install.wim , you’d type:

DISM can handle both these file formats ( .wim & .esd ), at least in Windows 10.

Running DISM command on install.esd

You’ll see the following output:

If you’re using Windows 7, running the above DISM command-line with the .esd file name parameter would throw the following error:

In that case, you can pass boot.wim as the parameter, as below: Running DISM command on boot.wim

Which results in the following output:

Note that for Multi-arch ISO files that include both 32-bit and 64-bit versions of Windows, the boot.wim, install.wim, install.esd file path varies slightly. These files are located under their respective architecture folders.

That’s it! You’ve now obtained the maximum information about the Operating System included in an ISO file, such as the OS version, edition, Service Pack level, architecture.

DISM Get-WimInfo showing the wrong version?

Sometimes, the Windows 8 or 10 ISOs may have the wrong version info (header?) causing the above DISM command to show the wrong version or build.

I downloaded the Windows 20 20H2 ISO (20H2 Build starts with 19042.nnn) from Microsoft.

• Filename: Win10_20H2_English_x64.iso
• SHA-256: e793f3c94d075b1aa710ec8d462cee77fde82caf400d143d68036f72c12d9a7e

Running DISM showed this:

Whereas, 20H2 build starts with 19042.nnn (as shown by the winver command)

The setup.exe (inside the 20H1 ISO) file’s version showed up as 19041.xxx, instead of 19042.nnn. So, it’s a glitch in this particular ISO.

So, be aware of the above issues. The above can happen sometimes.

How to Find Your Windows 10 Build Number, Version, Edition and Bitness

The Build Number, Version, “Bit”ness (32-bit or 64-bit) of your Windows installation can be determined using many ways, and here are some of the methods listed. Screenshots are from a Windows 10 PC, but most of the information applies to all versions of Windows.

Find Windows 10 Build Number, Version, Edition and Bitness

System Settings App

In Windows 10, use the System Settings app to find the OS information. Click Start, type About your PC. Click About your PC from the results.

System – Control Panel

Press Winkey + Pause-break keys. This opens the Control Panel → All Control Panel Items → System. Alternately, you can run sysdm.cpl directly.

Note: Since the Windows 10 v20H2 update, the following interface is hidden. Pressing the Winkey + Pause-break would take you to the modern Settings page instead. Microsoft is gradually porting items from the classic Control Panel to the Settings user interface. However, you can access the classic System panel by running this shell command from the Run dialog.

Using the DirectX Diagnostic Tool

Using WMIC (WMI command-line tool)

Open a Command Prompt window and type:

The WMIC command-line (mentioning “OSArchitecture”) tells you the bitness of your Windows. You can get as many details as you need using WMIC OS Get command, such as:

Note: Here is a complete list of fields you can retrieve using WMIC OS Get (which uses the Win32_OperatingSystem class)

In addition to all of the above methods, you can check the Help → About page any Windows desktop application like Notepad, Wordpad, Internet Explorer or others, for the Windows version & build information.

Note: The following methods don’t tell you whether you have an x64 version of Windows installed or not. They only show the OS installed and the System or Processor type (x86 or x64). System Type x64 means the processor is 64-bit. But that does not necessarily mean you have Windows x64. It could be Windows x86 OS running on an x64 CPU based machine.

System Information Utility

The System Information utility (MSInfo32.exe) has the details you need.

Scroll down and check the Hardware Abstraction Layer field. It also shows the full build number, including the minor build number.

About Windows (WinVer)

Alternately, in Command Prompt, run the ver.exe command to know the OS build number.

Watermark on the Desktop

If you’ve added the PaintDesktopVersion or the DisplayVersion registry values as in article Display Build Info, Version and WinDir Path in the Desktop, you’ll see the Windows Edition, Build Information and WinDir path in the desktop shown as a watermark. For evaluation versions of Windows, the watermark displays by default.

Using SystemInfo.exe Command-line tool

Open a Command Prompt window and type in:

The SystemInfo command outputs more information than you need. To get the OS Name and OS Version fields from the output, type this in the Command Prompt window:

The findstr command will parse the output and display only the two lines (OS name and version.)

Windows 10 Build/Version Upgrade History

Did you know that Windows 10 keeps track of your every build/feature upgrade in the registry? Redditor u/sizzlr has found an interesting registry location and wrote a PowerShell script to unscramble the Windows 10 build installation dates from the registry.

Every time you install a feature update, Windows 10 creates a new subkey named “Source OS (Updated on )” and a bunch of values in the right pane. The registry key is located at:

Additionally, there are two values, namely InstallTime and InstallDate, which store the install date and time. The following PowerShell script gathers all the details for you and presents in a table:

Do you know any other methods to find the Windows build, OS version and bitness? Let’s know in the Comments section below.

How to Check Windows 10 Build

To determine the build of Windows 10 that is installed, follow these steps.

1. Right-click the start menu and choose Run.
