The 70-528 exam was supposed to expire on March 31st 2009, but this is not the case now. If you want to know which exams have expired or discontinued then have a look at the
microsoft exam development website As the technology gets older, so does the exams and in this instance, there is no official word from microsoft when 70-528 exam will expire. Hope this helps,
