Running a 32bit or 64bit CPU?
Sometimes Windows alone might not be able to tell you what your machine has. To be absolutely sure, if you at least know you have an Intel CPU, try their Processor Identification Utility.
You can also save a text file report summary of your machine. Here’s my machine at work:

FYI, this is from Intel:
Certain advanced Intel(R) processor technologies require system support features be present to be fully enabled. Please see the notifications below for system features required to enable the listed technologies.
Intel(R) Hyper-Threading Technology
Intel(R) Hyper-Threading Technology requires a computer system with a processor supporting Intel(R) HT Technology and an Intel(R) HT Technology-enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. For more information including details on which processors support Intel(R) HT Technology, see http://www.intel.com/info/hyperthreading
To verify your system for Intel(R) Hyper-Threading Technology, download the Intel(R) Hyper-Threading Technology Test Utility from http://downloadfinder.intel.com/scripts-df/Product_Filter.asp?ProductID=1687
Intel(R) 64 Architecture
64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel(R) 64 architecture. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information.
Intel(R) Virtualization Technology
Intel(R) Virtualization Technology requires a computer system with a processor, chipset, BIOS, enabling software and/or operating system, device drivers and applications designed for this feature. Performance will vary depending on your configuration. Contact your vendor for more information.
