How to verify XP software you bought is OEM/UPGRADE/RETAIL?

I am sure we all have noticed Microsoft product marketing strategy.
Whenever they launch any new product line,there are various flavors of it
available right from day one. Some are given adjectives like UPGRADE
version or FULL, others RETAIL v/s OEM and then of-course we have various
categories of the product like HOME, PRO , SERVER , ADVANCED SERVER etc
etc. Well ever wondered what you bought is same as what was advertised ?
How to tell the difference. Here comes the help. Look for a file called
Setupp.ini that is present on your Windows XP CD and double click on it and
browse its content. There is a field called PID=. This PID is what would
tell us exactly what we have got.First 5 bytes of PID decide whether (it is
OEM or RETAIL or is an UPGRADE ) and last three digits determine what kind
of CD KEY will it accept. Here are some of the typical PID values:
Retail = 51882 335
Volume License = 51883 270
OEM = 82503 OEM
