I noticed a post this morning on the Windows XP Embedded team blog that I wanted to link to here to make sure everyone notices so this issue won't catch you by surprise. Official support from Microsoft for Windows XP Embedded SP1 is scheduled to end on April 10, 2007.
You can find more information about this at the following locations:
