As 64-bit processors are becoming more common it's becoming much easier to find 64-bit OS disks and drivers. Microsoft offers 64-bit versions of all forms of Windows Vista, although only Windows Vista Ultimate comes with the 64-bit version in the box. For all other forms of Vista it is possible to request a 64-bit version of the OS, but only after you have purchased a 32-bit version. The 64-bit copy is free with the exception of the shipping and handling charge.
