Just FYI. I have captured 3 ESD files today, two from the Windows Updater exe program and one from Windows Update directly. All three have been made into a WIM file (Option #1) without issue.
Okay, thanks all. I used the MCT which made the \ESD file that I found the install.esd in. I've since downloaded the ISO directly and upgraded everything I need to.
Thanks for all the responses, and special thanks to Kari for the great job he has done with this.
So it's just the install.esd from the C:\ESD folder created by MCT that does not work then, right?
No, it's all and every ESD file except the one created by Windows Update in C:\$WINDOWS.~BT folder.
That's the only ESD file this tool works with, that's the intention of this tutorial: to help you to make an ISO from a build upgrade got through Windows Update.
Ah, okay, I understand now. Thanks again Kari.
