I have recently upgraded to Vista and it looks like that it's working fine for me so here are some guidelines for you guys out there....



Upgrading to Windows Vista

If you are upgrading from Windows XP or 2000 to Windows Vista prior to the next release of iTunes, here are a few steps that will improve your experience when syncing your iPod or playing iTunes Store purchases once upgraded to Windows Vista.
  1. Deauthorize all iTunes Store accounts.
  2. Perform a clean install of Windows Vista (highly recommended but not required).
  3. Upgrade to iTunes 7.1 or repair iTunes using the iTunes installer if version 7.1 is already installed.
  4. Open iTunes.
  5. Choose Authorize Computer from the Store menu in iTunes.
