List Of Windows Os Code Names

Microsoft codenames are the codenames given by Microsoft to products it has in development, before these products are given the names by which they appear on store shelves. Many of these products (new versions of Windows in particular) are of major significance to the IT community, and so the terms are often widely used in discussions prior to the official release. 

 

 Microsoft usually does not announce a final name until shortly before the product is publicly available.There has been some suggestion that Microsoft may move towardsdefining the real name of their upcoming products earlier in the product development lifecycle so as to avoid needing product codenames
