Hello! I wonder if anyone has experienced this. I install Windows 8.1 64-bit Enterprise, remove all modern apps, log on as the built-in administrator account, delete all other accounts profiles and remove them from the local computer, customize settings, icons, and etc... then run Sysprep.xml. In my Sysprep.xml, CopyProfile is true to copy the profile to the default profile. Everything is good. I apply the wim file to three different machines all under UEFI 2.3.1. They all work. But on one of them, the Panasonic FZ-G1 ToughPad, when I re-image it, using the same wim image, the image applies but upon "Getting Ready", it gives an error, "Windows could not parse or process the unattend answer file for pass [specialize].......The error was detected while processing settings for component [Microsoft-Windows-Shell-Setup]. I know the error is related to the <CopyProfile>. But why it works before and on other machines and fails when I re-image it using the same wim file. Thank you and happy Thanksgiving!
