"PC search and win" refers to what is officially called PCHSearch&Win, or Publishers Clearing House Search & Win. It is a free Internet search engine that automatically enters you into PCH Millions, a Publishers Clearing House draw, the first time you use each day to make an Internet search.
Additionally, each and every search you make with PCHSearch&Win gives you a chance to instantly win a prize, like cash, gift cards and electronics. PCHSearch&Win's winners are chosen by an "instant win engine," which randomly chooses winning times every day. The first person to search at or after the winning time wins an instant prize. PCHSearch&Win is available on PC and mobile devices.
