The "old" dll that MS ships with WindowsXP is comctl32.dll version 5.x which is the same as on other Windows versions.
Version 6 is the new version. One of the biggest changes is that this updated dll handles both the user and common controls. Further all controls now include some area in which can be drawn for theming.

Another difference is that the new version comes as an assembly; multiple versions of the dll can live side by side.
