The preferred method is cutting a access hole or slipping in a thin stiff wire and undoing the locking device. Most double hung windows have cheap locks which should be replaced by heavy duty sash locks or even keyed locks, if you can put up with the inconvenience. An old trick is installing a small eyebolt in either corner. If done correctly the window can't be opened, with the eyebolt in place from the outside. Of course you could screw the window shut by drilling a hole through the frame but it defeats the purpose of having a window, and presents a fire hazard. Not recommended.
