I would like to know if it's possible to create a device (with an Arduino) connected to a PC via USB with any MAC address.
The unique objective is that the PC recognise the MAC address assigned to the device. (cmd, ipconfig /all,...). I do not need any connection/network with this device.
Thanking in advance.

If you do nothing with the device the PC won't recognize the MAC address as it will not see it. An inactive networking device is not visible on the network.
With an Arduino Ethernet Shield you can define any MAC address you like.
Please tell us what you want to achieve, we might help you more if you tell us more about your project.
My intention is to connect a device as we connect an USB WiFi adapter: the computer detect it (and reads it's MAC address) but you do not need to use it (for example because the computer is connected via Ethernet).
I would like to use this device as a "programmable hardware key" and if I connect to net this device changing the MAC address I could have MAC conflicts in the network.

So this is a Windows question not related in any way to an Arduino? If it's connected by USB why does it have to have a MAC address, any serial number would be equally useful.

As I already told you, a device connected to the network that is not active on that network is not visible, no attached PC will notice the MAC address unless the device has some network activity.
Maybe you should tell us more about what you want to achieve. In the last posts you told us how you think you should implement it but not what you're trying to implement. It sounds to me that you're trying to use the wrong technology to implement something trivial but I may be wrong because I have just a tiny amount of information.
