Since the launch, I have now (August 17th 2015) tested various Sysprep scenarios quite extensively. Customizing Windows with the CopyProfile
component set to True
(Parts Three, Four and Five in this tutorial) was causing issues in earlier builds of Windows 10. Either the Sysprep failed directly, or it caused an endless reboot loop when in OOBE (Part Nine), or it disabled the Start and Search / Cortana when done.
I now get 100% success rate and can replicate a successful Sysprep run with this simple workaround, Sysprep working perfectly every time and customization / generalization with CopyProfile
set to True
- Disconnect your technician machine used for customizing the Windows image completely from all networks before starting the installation
- Be sure that you install Windows 10 without entering the product key and without any whatsoever network connection
- When booted to Audit Mode desktop (Part Two), you can connect the machine to the network to download and install Windows ADK and software
- As Windows is not activated when booted to Audit Mode when following these guidelines you cannot customize the theme. Use a Windows themepack file instead, for instance creating the theme (colors, backgrounds, sounds, screensaver) you'd like to use for the default user profile on another computer and applying the themepack file on the technician machine before the Sysprep
You can now run Sysprep normally and without issues.
