Hi,
XP embedded needs Target Designer to build your own OS image.XP Pro for
embedded needs OPK(OEM Preinstallation Kit) to install your image.That
doesn't need any development tool like TD and any build effort.
So its installation method is easier than XPe.But its footprint is
huger and more expensive than XPe.Besides,Microsoft has some
limitations detailed in his license agreement.I suggest you to contact
your distributor for more details.
Thanks.
Best Regards,
