You can try this if you don't mind the network icon not showing that you're connected.
- Open Registry Editor (
- Go to
- There are subkeys numbered
0019. Look in each subkey in descending order (start from
0019) for the one with
DriverDesc value having your smartphone's RNDIS driver name (same name shown in your Network Connections view as the "Connect using" value).
- Once located, in the right side, right-click an empty area and select New > DWORD (32-bit) Value.
- Enter the name as *NdisDeviceType (remember to include the asterisk sign * in front).
- Edit the newly created DWORD value and enter the value data as 1 (Base choice doesn't matter). Click OK.
- Once done, in your Network Connections view, disable the network device, and enable it after a few seconds.
You will no longer get a prompt asking for network location whenever you connect your smartphone, but you will still get the prompt when connecting other devices.
Important Note: When you are only connected to your smartphone, your computer's network icon will continue to show that you are not connected to any network. However, the internet will still work fine.
