I recently got a Dell Laptop from a family member that has Windows 10 Home installed on it. The computer runs fine however it is constantly connecting to speedtest.net. The computer does not have any speed test programs installed. does anyone have any ideas for how to disable this?
You could use native tools like Resource Monitor to look at PID and see what application is calling out to speedtest.net. Also tools like Procmon, TCPView, Etc from sysinternals might be of some help.
Resolution: an application called smart screen by Rivet Networks, which is now owned by Intel, the manufacture of the wireless card in this system was the cause. Uninstalled the smart screen app and the connections outbound to speedtest.net disappeared. It seems the app is more unnecessary wifi crap. Thanks to everyone for the sigustions.
