Windows 10 x T29g

Hi, I have a T29G phone. We are having problems when using Windows 10 connected to the phone.
802.1x is disabled on the phone and enabled on the PC.
The switch port authenticates the phone, using its mac-address, and the PC, using 8021.x.
It works fine for all PCs with Windows 7 or Linux, but not works with Windows 10.

It seems that when the phone (with 802.1x disabled) is connect to the Windows 10, it is trying
to pass 802.1x authentication and it fails, even passing the mac-authentication it can not
get connected. The PC authenticates using 802.1x correctly and get connected.

So, why the phone is trying to authenticate using 802.1x even if 802.1x is disabled on the phone ?
And why this happens only when the phone is connected on a PC using Windows 10 ?
