What about Windows XP Embedded?

MS Windows XP Embedded, Version 5.1 SP2 has been Common Criteria certified. This gives embedded products a sound basis for the assurance of the platform.

I’ve been asked whether SP1 and SP3 have also been certified. They have not and it is understood that there are no plans to do so. Generally, for CC evaluations, we do not go back in time to evaluate older service packs and we do not re-evaluate a product when the next SP is released, especially when the next major version has been released.
