Notice that as has been discussed in the above mentioned tutorial thread, the CopyProfile component has a minor bug and we are waiting Microsoft to fix it.

Workaround is to completely emtpy the built-in admin desktop and recent files in Audit Mode before sysprepping, and removing the Desktop shortcut from the File Explorer Quick Access.
