There is two versions of Windows Xp, there is home and professional. The one to your left is Windows Xp Professional. This is the corprate edition of Windows XP. You would usually use it at a school or a business. It is better for networking, and you can also access your files remotely from a different computer. This version also costs close to 400 dollars for the full version, so if you are just using it for a home computer then get the Home Edition.

The Operating System to your left is Windows XP Home Edition, that was the one that I mentioned above. This is just for home use, the only real difference between this and Pro Edition is that Pro has easier networking, and the ability to access files remotely from a different computer. This Operating system is about 200 cheaper then the Professional Edition, which I think is a little over priced. Overall windows xp is a very good operating system. It is the best one yet that windows has made. It is very user friendly, it has wizards for everything.
