If you have an ISO file whose name gives you no idea about which build number, edition and supported platform is contained in it, here is a quick tip. Using the information from this article, you will be able to detect which Windows version is included in the selected file.
Here is what you should do.
- Double click the iso file to mount it in File Explorer.
- Open the "sources" folder and see which extension has the largest file by size, named "Install". It can be install.wim or install.esd: Note, some ISO files of Windows 10 can combine 32-bit and 64-bit setup files. If you have such an ISO image, you will find the "sources" folder in the following location:
Also, you will need to correct the commands below to include x86/x64 portion in the path.
- Now look at the address bar and see which drive letter File Explorer assigned to the opened ISO file. In my case it is F:
- Open an elevated command prompt.
- If you have the file install.wim, then type the following:
dism /Get-WimInfo /WimFile:F:\sources\install.wim /index:1
Replace F: with the appropriate letter after the WimFile: part
If you have the file install.esd, then type the following:
dism /Get-WimInfo /WimFile:F:\sources\install.esd /index:1
For a multi-architecture ISO file, as mentioned above, you will need to use commands like
dism /Get-WimInfo /WimFile:F:\x86\sources\install.esd /index:1 dism /Get-WimInfo /WimFile:F:\x64\sources\install.esd /index:1 dism /Get-WimInfo /WimFile:F:\x86\sources\install.wim /index:1 dism /Get-WimInfo /WimFile:F:\x64\sources\install.wim /index:1
- You will get the following output:
Using the output, you can determine what the build number is of the ISO image, what the supported architecture is and which edition and which language is used by default in the install.wim file. In my example, it is Windows 10 Technical Preview x64 English, build 10.0.9988.
