SUMMARY
This article lists the technical specifications of guest PCs in Virtual PC 5.2.



MORE INFORMATION
The following is a list of technical specifications that apply to guest PCs in Virtual PC 5.2:  Processor

The emulated environment &quot;sees&quot; the same processor model as the processor of the host PC. For example, if the host PC contains a Pentium III processor, the operating system of the guest PC reports that it runs on a Pentium III processor. The guest PC supports the same functionality that is available on the processor on the host PC. The guest PC supports features that include any the following if these features are also supported by the processor of the host PC:  Multimedia Extensions (MMX) Streaming SIMD Extensions (SSE) Streaming SIMD Extensions 2 (SSE-2) 3DNow
