According to latest reports Windows XP users will not be able to enjoy iCloud, the clouding service of Apple.
Among the minimum requirements for the use of iCloud, reads:
iCloud requires Windows Vista or Windows 7
This means that iCloud will not be compatible with Windows XP, which is still one of the most popular operating systems and widely used all over the world.
iTunes 10.3 and MobileMe, however, still support Windows XP, indicating that these are the latest versions of software available for that operating system. If you are using Windows XP, it is advisable to upgrade your computer to Windows Vista or Windows 7 in order to be able to use iCloud on your computer.
