  • Question
    If I dual boot, will the MAC address remain unchanged after I switch to Windows through restart?
    Community Answer
    Not necessarily. Every hardware network device (e.g., WiFi card) has its own MAC address. However, sometimes the OS (Windows or Linux) changes the MAC address. It differs from system to system and from configuration to configuration.
