Some Windows OS does not have a native option for formatting a drive in FAT32 format through the GUI; it does have the NTFS and exFAT file system options, but these are not as widely compatible as FAT32.
While Windows Vista does have a FAT32 option, no version of Windows can format a disk larger than 32 GB as FAT32.
Therefore, to format a drive in FAT32 format, you will have to either use a third-party FAT32 format utility, or manually force Windows to format your drive as FAT32 from the command line using diskpart.
