There is XP Home; XP Pro; XP Media Edition; XP Pro x64
The latest version of each is SP2.
If a disk or system is labeled Corporate it is either a Volume Licensing version purchased and installed by a corporation (this would be XP Pro) or (if it is for sale) a pirated version.
i am using windows xp pro sp2 ... are there any extra features in the windows xp sp2 pro corporate edition that is not there in windows xp sp2 pro edition ?
