When you supply a SysPrep answer file, SysPrep may not process the answer file as you expect. The Mini-Setup wizard stops processing and requests user input.
One cause of this may be the use of comments within the SysPrep file. Sysprep.inf comments are denoted by the semi-colon (;) character. When a comment character is included on a line in the Sysprep.inf file, the complete line is omitted from processing.
Move the comment to a separate line of its own.
