Hyper-Threading Hyper-Threading is an Intel® technology that can enhance overall performance by allowing one physical microprocessor to function as two logical microprocessors, capable of performing certain tasks simultaneously. It is recommended that you use the Microsoft® Windows® XP operating system because Windows XP is optimized to take advantage of HyperThreading technology. While many programs can benefit from Hyper-Threading technology, 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 on using your software with Hyper-Threading. To determine if your computer is using Hyper-Threading technology: 1 Click the Start button, right-click My Computer, and then click Properties. 2 Click Hardware and click Device Manager. 3 In the Device Manager window, click the plus (+) sign next to the processor type.
