Windows – Mac address changed after windows automatic update

addressmacwindowswindows-update

My computer and that of a collegue have a changed their adress when booting up this morning. The only thing I can think of right now is the windows automatic update which has kicked in tonight to deliver and install KB2286198, which doesn't really talk about this.

Is anybody else seeing this behaviour or should I be worried something else is going on behind the scenes?

you don't have to worry ! If you MAC address has really changed the only direct issues I can immagine are wireless authentication based on MAC Adresses. If so, go to te admin interface and update mac addresses you allow to join the network.

May be you can also have dhcp / fixed ip issues. But if you don't use any of them, it's ok.
