Use random hardware addresses to stop Wi-Fi tracking
When your laptop isn’t using Wi-Fi it looks for networks nearby to connect to. It does this by sending a signal that contains its MAC address. Because this address is unique to your device, some public areas like shopping centres could use it to track your movement.
You can block this by getting Windows to generate random MAC addresses, concealing your real one. There are two ways of doing this – either across all Wi-Fi networks (for maximum security), or on specific networks. To do the former in Windows 10, open Settings (press Windows key+I), then click ‘Network & Internet’ followed by WiFi on the left ( in our screenshot below). Now click the ‘Use random hardware addresses’ slider so it turns blue (on) .
