Note that there is normally no need to specify the build numbers (i.e., you may simply use "5.1" for Windows XP).

If a major version number less than 5 is specified in combination with a one-digit minor version number, the minor version number will be multiplied by 10. Therefore, 4.1 (Windows 98) is equivalent to 4.10.
