The Windows Appaearance has one ugly bug at least in Windows 98, 2000 and XP: the weight of typeface used in menus. Normal menus are drawn with weight 400/0x0190 (Regular), for default item Windows adds 200 weight units. This produces 600 for which there is no corresponding font. An automatically calculated semi-bold text is used instead. To get nice 700 (Bold) weight for default menu items, one can use 500/0x01F4 for regular text.

Here is the Windows 2000 color scheme modified for proper Bold:
