Chapter 1. Introducing Windows XP > Security Differences Between XP Home and XP...

Security Differences Between XP Home and XP Pro

Since Windows Server versions are not going to be discussed to any great degree in this book, let's get back to a more relevant task at hand—comparing XP Home and Pro. As we discussed previously, there are a few software features that differentiate the two, such as Remote Desktop. But there are also some salient hardware and security issues worth some scrutiny. Let's look at these a little more closely.

Hardware-related Differences Between Home Edition and Professional

As mentioned in a list earlier, XP Professional supports Symmetric Multi-Processing (SMP for up to two processors), whereas Home Edition doesn't. Since there are many dual-processor systems around these days, and prices have dropped (SMP-capable Athlon- and Intel-based motherboards can be found at well under $300 and a couple of speedy processors for about the same), this is a serious consideration. Actually, Microsoft did a bunch of research on this issue and decided that since so many of its older consumer-based products didn't support multiple CPUs—not DOS, not Windows 3.x, and none of the Windows 9x product line—they'd continue the trend. The moral here is that if you have a dual system, or see one in your future (either AMD or Intel are supported), XP Professional should be your natural choice.
