Thanx @Kyhi - I have added it to my toolbox...
I have created this tool Releases Â· Superfly-Inc/Windows-ISO-Creator Â· GitHub
@NavyLCDR suggested a link in Showkey from the screen showing the edition to a link that will automatically download the correct version of Windows 10.
In EsdIso, selecting Win10 and sub-selecting edition will include Win 7 editions and download the correspronding Win10 edition for upgrading.
But what I'd like to know... you'll see there is a WinPE option - is it possible to create a workable (boot to Desktop) WinPE ISO from the ESD file? (i.e without ADK)
