The GetProductInfo() function returns pdwReturnedProductType as a numeric type argument.
Is there a function to convert this number to a name?
Or, can you suggest to me a really full list of such product name constants? The MSDN article is missing some values, like 0x59 - "Industry Pro (Embedded)".
Look at the OSEdition Enumeration defines on MSDN, it has the numeric values you are looking for, including 0x59:
This section provides the product enumerations for the OSEdition element.
#define PRODUCT_EMBEDDED_INDUSTRY 0x00000059
AFAIK, there is no function to convert these numeric values into human readable names.
