I'm not 100% on this discussion but I'm behind a Windows 7 machine at the moment so and not able to inspect of a font has a certain table, but Notepad does not apply kerning to Tahoma. It does apply kerning to a font from Adobe, for example Adobe Garamond Pro. Notepad does apply kerning for Calibri, a "newer" MS font. So I think for all "new" system fonts kerning is applied. So I assume they have a kern feature (and Tahoma does not).
Does this help? Is there a easy tool for Windows to output these features per file?
