iPod for Windows Software Updater is tool for the software that controls iPod.
First, it is important to understand the difference between "update" and "restore."
"Update" simply updates the software that controls iPod and does not affect the songs and files stored on iPod.
If you want to update your iPod on a PC, it must be formatted for a PC. If it is not, you will see a message stating that your iPod needs to be reformatted. If you receive this message, refer to Restoring iPod to factory settings before proceeding. Depending on the iPod model and whether you use USB or Firewire to connect to your iPod, you may be asked to leave your iPod attached to the computer for the update to complete, or you may be asked to connect the iPod to the power adapter.

A PC with built-in FireWire or a Windows-certified FireWire card, Windows Me, Windows 2000, or Windows XP Home or Professional
