Microsoft codenames are given byMicrosoft 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 ofWindows in particular) are of major significance to theIT community, and so the terms are often widely used in discussions before the official release. Microsoft usually does not announce a final name until shortly before the product is publicly available. It is not uncommon for Microsoft to reusecodenames a few years after a previous usage has been abandoned.
There has been some suggestion that Microsoft may move towards defining the real name of their upcoming products earlier in the product development lifecycle to avoid needing product codenames.[1]

The first release of Windows NT was larger and slower than expected, so the next major push was a project called Daytona, named after the speedway in Florida. The main goals for this release were to reduce the size of the system, increase the speed of the system, and, of course, to make it more reliable.
Windows 10's next major update is codenamed 19H1.
This means the next Windows 10 update, previously codenamed 19H2, will be called Vanadium (comes after Titanium/19H1).
