Windows XP comes is several different flavors. There is Home Edition, XP Professional, XP Server and XP Advanced Server. I decided to do a review of the Professional version, since it will have more features that I can report on (this review will need to have many different parts since there is so much new stuff to report on). Some of the features that Windows XP includes are remote installation, remote control troubleshooting, direct writing to CDs without using third-party software, system restore, device driver rollback, Internet connection firewall, increased application compatibility (by using run in compatibility mode - more on this later), web update of files before installing the OS, wireless networking and many others.
