Somehow, this just does not sound right. Each of the items listed by Jazzymjr are changed individually in the Windows advanced settings so I would think that could be done in SKS. The Icon test inWindows controls the text in Explorer. Don't know if this helps.
You and I are both right Frankief. In SKS, the font that controls the text on all buttons, icons, and Explorer, along with just about everything else, except for Title Bars, User Names in XP on the start menu, is the main system font that has been set by the skinner. For example, I use arial for my system font, and it shows up all over the place in the blind.
S J N, if you are trying to change a font in someone's else's skin, you could always contact the author of the blind, and ask him/her about changing the font.
