Most people need all the help they can get when they buy a new PC. Give them bad advice and theyre very likely to take it. Lately, Ive been hearing and seeing a lot of advice that home users should use Windows XP Pro. Usually the reasoning is some vague variation of "its more secure."
Not only is this bad advice, its actually worse advice than it used to be. There are basically three editions of Windows XP: Windows XP Home, Windows XP Pro, and the new Windows XP Media Center Edition. Think of Media Center Edition as a hybrid with some entertainment-related features. Ill go into more detail below.
From the outset, XP Pro had very few features that Home lacked, but they were important features. The most important one has always been the ability to log into a Windows domain. The others of importance are support for EFS (Encrypted File System) and the ability to act as a server for Remote Desktop Connection.
As of the 2005 Edition, Windows XP Media Center Edition has EFS and Remote Desktop. EFS is certainly a security feature, although not one frequently useful for home PCs, even for home notebooks. As much as I like Remote Desktop, I have to engage in some serious sophistry to call it a security feature. There are a number of other feature differences, mostly obscure or very high-end. Here is Microsofts explanation, from the Media Center Edition 2005 FAQ:
Since Windows XP Media Center Edition 2005 is a superset of Windows XP Home, and they are priced the same, theres no reason to buy XP Home. This also leaves the ability to log into a Windows domain as the only reason left to prefer Windows XP Pro to Windows XP Home.

Logging into a domain is a very important feature for clients on managed networks, where numerous important security features then come into play, including the ability for administrators to control the desktop appearance and rights of users; to install and remove applications on their desktops; and to control their access to network resources. But logging into a domain is not a feature for which many home users have a need, because almost none of them have access to a Windows domain.
