ISO File:
Please notice that the ISO file of this Windows XP Embedded build is posted because it took a long time for me to find an ISO file of this build that was available for download and the file is no longer available to download from Microsoft and there's lack of download mirrors of this ISO file available, which made the ISO file hard to get.
