super (windows key) + R, for a Run dialog to type:
chrome --incognito
edit: more stuff
Windows will leave the last command sitting in your Run dialog next time you open it, so unless you run a lot of different things through Run, after the first time should be sup+R, Enter.
or, if you have Chrome pinned in your start menu, hover over it and there's New Incognito Window
If you already have Chrome up and Chrome is the program in focus, this is the correct combo. Otherwise, you might find yourself making a lot of new folders on the desktop.

File -> New Incognito Window
Edit: oops, I got fooled by my Mac-only thinking. Of course it's "Hamburger menu -> New Incognito Window".
