Windows XP users will not be able to take advantage of iCloud, according to Apple’s press release.

While Microsoft’s 2001 desktop operating system is still the most popular operating system in the world, iCloud isn’t going to support it. As outlined in Apple’s press release:

Using iCloud with a PC requires Windows Vista or Windows 7; Outlook 2010 or 2007 is recommended for accessing contacts and calendars.

Interestingly, iTunes 10.3 (which adds a beta version of “iTunes in the cloud“) still supports Windows XP. However, as TUAW notes, this may indeed be as far along the Apple-line as the aged operating system is going to go. After all, it is almost 10 years old.

If you’re an avid Windows XP user, let us know if you’re planning on upgrading your operating system for iCloud in the comments.
