Welcome page in Visual Studio Code How to get it

You have to use the command palette (either press F1 or click View -> Command Palette...), then start typing Welcome and select Help: Welcome option.

This can now (May 2017) be accessed via the standard menu: Help -> Welcome

It looks like the name of the welcome page got changed into "Get Started". To open the "Get Started" page:
Click in the menu:

Help -> Get Started

Or type in the command palette:

">Get Started"
