How to disable Media Sense in Windows 7?

Applies To: Windows | Windows 7 | Desktop and Personalization

I have updated the DisableDHCPMediaSense value in the registry but I am still getting "Media Disconnected" when the network is unplugged.  This is causing an issue because some of the software we use requires the IP to be licensed.  Does anyone know another (a) way to disable the Media Sense feature for Windows 7.

Thanks in advance for help.

Hi Wes C,
To disable Media Sense, please perform the following steps:
1)     Click on the Start button.
2)     Type cmd in the search bar.
3)     Right click on the cmd.exe and select Run as Administrator.
4)     Run the following commands one by one:
netsh interface ipv4 set global dhcpmediasense=disabled
netsh interface ipv6 set global dhcpmediasense=disabled
5)     After finishing the commands above, please run the following commands to check the results:
netsh interface ipv4 show global
netsh interface ipv6 show global

Please check if the entry “DHCP Media Sense” shows disabled or not. If it is disabled, it means the operations are successful.
However, please also note, the Media Sense depends on the NIC; if the NIC didn’t support the Media Sense, the configurations won’t take effect, either. Therefore, please also check the issue with the technical support of your NIC.
For more information, please refer to the following documents:

Did anyone every find out how to fix this in WIN7 I need the nic to stay up because our license is tied to the nic.

DisableDHCPMediaSense=1 does not seem to matter. I have a Lenovo laptop with Intel NIC.

No...after working with Microsoft for a while it was determined that Microsoft has designed the operating system to require a network connection.  I had to write a service, to fix our licensing issues.

I have the same problem. I always have to boot, log in to windows, go to regedit, just edit the  DisableDHCPMediaSense=1 entry (it is set at 1 but it does not seem to matter unless I go there edit it and relog) reboot, then I am able to work normally. Any help/service/dll/script/whatever would be greatly appreciated.
