"To check your PID press the win key and pause at the same time, or open system properties through the control panel, scroll down to activation section and look at the PID It will look something like this 12345-067-1234567-54321.
The portion you are interested is the three digit section of the product ID number, if it matches or is within one or two digits of the examples below you probably have an MSDN or TechNet product key." These keys are not to be sold for retail use.
065, 066, 067, 068, 069 for Ultimate, 220 area for Professional and 230, 231, 232 area for Home Premium,
There are probably others but they should be close to those posted"
(How to be certain - Download the Microsoft Genuine Advantage Diagnostic Tool listed above).
Note: Although sold illegally MSDN/TechNet product keys allow for more than one activation (typically 5 or 10), Therefore these keys can be sold "multiple times" before activation may fail.
