How do you check the current duplex value of a network card set to Auto negotiate in Windows?

I would like to know what duplex (half or full) my network card has negotiated with a switch when they are both set to auto configuration in Windows.

"At command prompt:

powershell ""Get-NetAdapter | SELECT name, fullduplex | where name -eq 'card name'""

Enjoy."

"Type the following into command prompt:

wmic NIC where NetEnabled=true get Name, Speed

It should tell you."

"This works in Windows 7, not sure about lower versions:

Right click on the network card in Network Connections in the Control Panel
Click Configure
Click the Link Speed Tab
Look at the Link status Window."

"There's no need to spend an hour in the event viewer :

Inside ""Network Connections"", right click -> ""Status"".

Here you can see ""Speed""."

Yes it's easy to see the speed 10/100/1000Mbps, windows tells you and the LEDs tell you, the person was asking about Full/Half duplex, which can be at any connection speed 10/100/1000Mbps.
