XP Professional and XP Home Edition share the same kernel (the "guts" of the operating system), and this kernel is based on the Windows 2000 operating system. The differences between them are in the level of security they provide, networking capabilities, and advanced features. For business users, Windows XP Professional is very similar to Windows 2000 in it's feature set. XP Professional supports multiple processors, multiple monitors (up to 9), Group Policy. Encrypting File System, Dynamic Disks, IIS, a built in backup program, and advanced networking capabilities (such as IPSec.) All of these features are missing from XP Home Edition. Another important distinction between the two versions is that XP Home Edition cannot join a Windows NT/2000 domain. If you wish to network with other PC's in your home or office, you must be part of a workgroup. If you're a "power user" purchasing Windows XP for your personal workstation, Windows XP Professional is a better choice than Home Edition, if you can afford the price difference.
