# How to determine Windows version from ISO file

You can gather Windows information from ISO file using DISM in two easy steps:

1. Mount the ISO file. Note the drive letter;
2. Open elevated command prompt and start:
`dism /Get-WimInfo /WimFile:F:\sources\install.wim /index:1`

Replace F with the drive letter of mounted ISO file.

The output will be similar to this one (I’ve highlighted interesting parts):

`Deployment Image Servicing and Management tool`
`Version: 10.0.14393.0`

`Details for image : F:\sources\install.wim`

`Index : 1`
`Name : Windows 10 Enterprise`
`Description : Windows 10 Enterprise`
`Size : 13,966,855,560 bytes`
`WIM Bootable : No`
`Architecture : x64`
`Hal : <undefined>`
`Version : 10.0.14393`
`ServicePack Build : 0`
`ServicePack Level : 0`
`Edition : Enterprise`
`Installation : Client`
`ProductType : WinNT`
`ProductSuite : Terminal Server`
`System Root : WINDOWS`
`Directories : 19036`
`Files : 103740`
`Created : 7/16/2016 - 4:58:32 PM`
`Modified : 7/16/2016 - 4:59:29 PM`
`Languages :`
` en-US (Default)`

`The operation completed successfully.`

This works for Windows 7 and later installation medias.
