If you are using a mouse or trackpad, just move the mouse cursor to the right of the screen and then move it downwards. If you are using a touchscreen, simply swipe in from the right side of the screen and the Charms bar should appear.
The charms bar is usually hidden from view. It can be revealed - by sliding your cursor to the right of the clock. If you move your cursor off the charms bar - is slides back out of view.
About the best we can do here, is Windows+C to open the charms bar. Then click or tap the corresponding entry to perform the feature.
