The trouble is, Cortana is consistently effective at doing whatever search you don't want. If I want to do a general web search, it doesn't show me web results, it just shows me apps that are vaguely similar (whether I have them installed or not). But if I want to run a program I already have installed, instead it will take me to the web page to install that app. You think Cortana is a waste of space and time for file and folder search? Then you can bet your sweet bippy that's all Cortana will do for you.
