One pesky problem with Windows 10, as well as the earlier versions of the Microsoft Windows operating system, is that the COM port assignments for devices that use them, often change. In this post, we show how to change COM port number on USB modem back to what it was before. Or, you can do this to changed assigned port number at will to any unused port you desire.

A USB modem for example, may start off being assigned to COM3 when you plug it in right out of the box. But that assignment can (and often does) change to COM4 or some other COM port, any time the modem is unplugged and reconnected, the computer restarts, a new version of a device driver is installed, a different USB port is used, certain Windows updates are installed, and a myriad of other possible port reassignment triggers.

Of course, when the modem COM port changes, any program that relies on the modem listening on the original COM port, no longer functions correctly. The solution is to change the modem COM port back to the one it was originally using, and the procedure below demonstrates how to do this.
