Error Message: Sysprep was not able to validate your Windows Installation. Review log file at %WINDOWS%\System32\Panther\setupact.log for details.

Overview: This error is due to Windows Store updates between the time Windows is installed and running Sysprep. It is possible to solve this issue via PowerShell, see here https://learn.microsoft.com/en-us/troubleshoot/windows-client/setup-upgrade-and-drivers/sysprep-fails-remove-or-update-store-apps HOWEVER, a re-install using the auto-install disk is much quicker and more reliable, see instructions below.
