For the font *size*, you could try this (It's a windows setting)

Right-click on any empty space in the desktop choose Properties

Select Appearance tab Advanced button
(in Win XP)

In the Advanced Appearance dialog:
Click on "Item" dropdown menu choose Tooltip
Choose a font size OK Apply

To change font *type*, try Debra's page at:

(Look for the header: "Insert a Formatted Comment")
