I have an old laptop that I want to setup for Haley to access her school programs. My only catch is that it is an XP laptop, so the security is effectively wide open. Specifics to the network setup: - Google Wi-Fi - I have a guest network available, but would prefer to not have to log into it all the time. Do I have any options when it comes to protecting our network when I have this computer on it? Do I need to do anything in general when I have the Google Wi-Fi guest? Onto the laptop, what is the easiest way to make sure that everything is deleted off a computer? I want to make sure that everything except Chrome and the Office suite is off that computer.
