Locate the Bluetooth Icon in the icon tray. This will be located in the lower right-hand side of your surface screen.
Right-click on the Bluetooth icon and Left-click on Show Bluetooth Devices.
You will now see available Bluetooth Devices. As you will note, the Pen is not yet available to your Surface. At this point, you will need to hold down the purple button at the eraser end of the Surface pen. Hold the button down for roughly 7 seconds.
If done correctly, you should now see the Surface Pen. Left-click on the Surface Pen icon and select Pair at the bottom right.
