Windows 10: How does the MS RNDIS driver work?

I recently purchased a 4G/LTE USB modem to use on a laptop. It uses the MS generic RNDIS driver. I can also attach my cell phone (in "tether" mode) to the laptop. That also uses the RNDIS driver. When I connect the USB modem something - and I assume that "something" must be the driver - invokes my default browser (Firefox) and automatically connects to modem's admin/management HTTP server. When I connect the cell phone the browser is not invoked. I don't understand the invocation of the browser. I double checked to make sure it's not an Autoplay/Autorun setting invoking the browser but I have them disabled. (And I don't think Autorun could have set the IP addr anyway.) Would the driver really be built to invoke a browser? The only alternative I can think of is that data from the connection (which looks like Ethernet over USB, I think) could automatically invoke my default browser. I hope that's not possible. BTW, the operating system is Win 10 20H2, but I don't think that matters much.

RNDIS USB Modem Dongle is not working after installing Windows 10 Fall Creators Update

Hi,

Updated 1/31/18:

A fix for this issue was included in the
January 31, 2018 Windows Update (KB4058258). If you are experiencing this issue, please install the latest Windows Updates.

If the issue continues after installing the update, you may need to uninstall and reinstall your Remote NDIS network adapter using Device Manager:

• Open Device Manager. To do this, press and hold (or right-click) the Start Menu icon and select Device Manager.
• Expand Network adapters and find an entry for the Remote NDIS based Internet Sharing Device.
• Right click Remote NDIS based Internet Sharing Device and select
  Uninstall device.
• Select Network adapters and then select Action and then
  Scan for hardware changes.

Note:

• Ensure that the RNDIS device is plugged in on the PC's USB when performing these steps.
• If the RNDIS device is moved to another USB port, these steps will need to be repeated.
