Now, whenever your friend starts complaining about a computer issue, open your home computer click the video-camera icon on the contact page to initiate a video call. Once the video feed goes live, hit the plus button down by the call options and choose Share screens. From here, you can continue chatting while you watch them demonstrate the tech issue in question. Ask them to carry out any troubleshooting steps you think are necessary, and see how their machine responds. When you're done, go back to the normal two-way video feed by choosing Stop sharing from the same menu as before.
