I think you were using some 3th party software for auto completion. There was project called Visual Assist with was pretty popular and powerfull tool.

Visual Assist provided much better completion especially for (then brand-new) C++98 if you used templates, STL etc heavily, but VC had its own completion out of the box that was actually pretty good for plain C code like Quake. AFAIR the "IntelliSense" branding was also in place already.
