Unattend setup w8.1 can be easy interrupted?

[romboman]

Hi all,
during unattend setup it's possibe to interrupt the install process by clicking the close window button (see attachment)
Is there a solution to hide/disable this button or hide the installer progress window (option in unattend.xml)?

Thanks!

Maybe a resource hack on spwizimg.dll bmp's 506-510
