Determining Windows 10 ISO Build

Windows 10 releases are numerous. If you are using Microsoft Media Creation Tool to download ISOs, you know how hard is to track them. Fortunately, it is possible to get information about version from ISO file itself.

First order of business is mounting downloaded ISO file. It is as easy as double clicking on it.

Then find Setup.exe; right-click; Properties; and go to Details tab. There under product version you will find the build number - in my case it was 15063.

If you want to know more (e.g. which editions are present in .iso file) we need to open Administrator command prompt (or PowerShell) and run [dism](https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/what-is-dism). I will assume, ISO is mounted as disk W: and that your download includes both 32-bit and 64-bit Windows. Adjust path to install.wim as needed.

As you can see, this disk consists of four editions. Which one gets installed is determined based on your product key.

And you can go even further with investigation, if you give it index parameter:
