At work: How can I mention some reputable achievement that I've just earned?

I work as a retail IT support person, at least I’m supposed to. Recently, however, we’ve gotten a new supervisor (who has no background whatsoever in IT) who has forbidden me to work in the back on computers, making me more of a very knowledgable secretary. I asked why, and was told that I hadn’t done anything wrong (which I was sure I hadn’t), but unlike the other people working there, hadn’t been formally trained (which none of the other part-timers actually have). However, there’s been no mention of me actually being “formally” trained, whatever that means.

Long story short, I’m working on some Microsoft certifications in Vista Configuration and Consumer Support Technician.

My question is this: what would be the best way to let them know that I’m certified, once I am, and perhaps let them know that I’m serious, and just as capable as anyone else there of turning services on or pressing “start” on an antivirus scan.
