Hyper-Threading
Hyper-Threading is an Intel® technology that can enhance overall computer performance by allowing one physical processor
to function as two logical processors, capable of performing certain tasks simultaneously. It is recommended that you use the
Microsoft® Windows® XP Service Pack 1 (SP1) or higher operating system because Windows XP is optimized to take
advantage of Hyper-Threading technology. While many programs can benefit from Hyper-Threading, some programs have not
been optimized for Hyper-Threading and may require an update from the software manufacturer. Contact the software
manufacturer for updates and information about using Hyper-Threading with your software.
To determine if your computer is using Hyper-Threading technology:
1. Click the Start button, right-click My Computer, and then click Properties.

processor is listed twice.
