Find Windows 10 ISO Version or Build Number

Details

Finding the Windows 10 ISO version or Build Number is important because builds starting in November 2015 and newer allow you to clean install Windows 10 if you have Windows 7 or Windows 8.

  • -mount the ISO to expose the files. This can be done through Windows 10, if you have another computer available or through VirtualCD.
  • -find where the "install.wim" (or install.esd) is. For example; F:\sources\install.wim
  • -open CMD
  • -type: dism /Get-WimInfo /WimFile:F:\sources\install.wim /index:1
  • -or if Windows 10 install.esd file, type: dism /Get-WimInfo /WimFile:F:\sources\install.esd /index:1

This will show the details of the INSTALL.WIM file.

NOTE:

-in some cases, Windows-7 will not be able to read a Windows-10 install.esd file :-(
