I have been asked a question about how does Snow actually differentiate the SQL editions (Std and Ent). Obviously in the background it is doing some jiggery-pokery activity, is it linked to .exe of something more glamourous.
The recognition is based on the entry in the registry from "Add/Remove Programs" for the SQL Server instance. It contains the edition name (Standard/Enterprise/Developer/Express).
You can see that yourself in the SLM SMACC.
