I have to say I have very good results from this script, we don't upgrade Windows 7 systems with it only WINDOWS 10. I use Sharepoint to host the file for users that can't reach a DC. I create a cache folder on \\blah.local\NETLOGON\cache and copy the latest ISO there so everyone has access and add the \\blah.local to the Extra 1 field. Mad props to the creators of this has saved me soooo much time.
