Windows 10 v1909 Mac randomization on boot
I upgraded to Windows 10 version 1909 around the beginning of January 2020. Ever since then whenever I boot my computer up fing warns me of a new Mac address and blocks it. I have it setup to auto block new devices. Literally everytime my computer boots up a random Mac address is identified by fing. I've looked them up and I don't see any connection to any manufacturer or device. I've checked my actual real Mac address and it's nothing like the random ones being generated. My desktop is set to DHCP. If I unplug my ethernet cable and reboot, no random Mac. If I disable the network card in Windows settings and reboot, no random Mac.
According to fing the device goes offline within a minute of it going online. Fing shows it has no ip associated with it. I've tried safe mode with networking and the random Mac happens. If i boot into diagnostic startup only same random Mac happens. I am wondering if Microsoft introduced something to 1909 that would make this happen. I also thought maybe malware might be calling home and did run scans with Malwarebytes, windows defender and Avast. All clean.
Anyone have any ideas?
