Lauren's laptop has green horizontal lines. She tried to restore her OS and that seemed to fix the lines issue, but now she's dealing with Windows installation issues. Leo says that's interesting because the green lines usually point to a hardware issue. Leo says that it's important to install all the updates, otherwise she's vulnerable to security issues.
Lauren says the updates get installed, but everytime she uses the computer, it asks to install more updates. Leo says that a failed update may cause the computer to keep trying to install. Stuck updates can be removed so she can move on. As long as it's making progress, she should keep rebooting until it's done. Updating with Service Packs is also helpful. Leo warns that those green lines may come back, though.
