How to get LTSB revision number from ISO

There are monthly (give or take) revisions to the various Windows 10 Builds, for example, LTSB 1607 has almost two dozen Build Numbers corresponding to KBs and release dates, such as 14393.1198 (released 5/9/2017) or 14393.693 (released 1/10/2017). We've found a spot where these specific builds are noted in the registry of an installed and running Win10/LTSB1607 machine.

But, is there a way to find that build number (specifically the number after 14393) on the ISO downloaded from Microsoft?

We've got a couple of the ISOs floating around, and we'd like to know if we can determine which ones are which. We can't just use the date of the files, and most the data on finding "language/edition/build/architecture" ends at "14393". We're interested in using the most recent ISO build because bandwidth at satellite locations is extremely limited, and downloading multiple Windows updates after installation of an older ISO is a problem. So we would like to get the current revisions out to each of those sites, but we're not sure how to ensure what revisions are already there.

Would we just be better off using whatever revision we have and creating a custom patched/updated installer? Would a current revision be smaller and faster than using that revision and slipstreaming updates (or using MDT)?

Solution 1:

Mount the ISO, and use the Get-WindowsImage powershell command against the install.wim. The Version should be what you want.

PS C:\users> Get-WindowsImage -ImagePath h:\sources\install.wim -Index 1
