possibly Verdana.....looks similar to my friend's font on aim....which is verdana, bolded i think too. not sure what size. theres a certain combination of verdana, bold, and size that makes it look just like that, otherwise its scewed slightly.

Verdan all caps, bolded.

It's the most used font in Windows GUI.
