Genuine UNOIs this a genuine arduino or a clone?
Yes tried that, still get COM4 only. I have another Arduino and it shows COM4, COM6. Wonder if this one has failed. Any way of telling from error msg. The green and Amber lites come on OK.And you are using the Arduino IDE? You need to find the “Ports” option in the menu drop down. Click on it and see which port is selected. Other ports will be listed and the active port (COM4, COM6 or another one) MUST be selected.
Check the Help option for assistance in setting the correct port. Oftentimes, unplugging the Arduino and closing ALL instances of the IDE will help. Then plug in the Arduino before starting the IDE, and the correct port will appear in the drop-down.
I have 2 Arduinos, 1 has a green and amber light when plugged in, the other has a green and 3 amber lights (1 RX, 1TX) that light when plugged in. Not sure why this differenceAnd you are using the Arduino IDE? You need to find the “Ports” option in the menu drop down. Click on it and see which port is selected.

Yes, only one connected at a time.Do you only have one Arduino connected via USB at a time?
If you only have Com4 showing, that’s where the Arduino is connected.
Tried, only shows LPT no Arduino when USB cable is connected. Looks like for some reason, it does not recognize that Arduino is connected. Also, both the TX, RX LEDs are lit which is not the case with my other Arduino.The number of leds lit on your Arduino will depend on what software has been loaded into it. I doubt whether anything is wrong with your two Unos.
You need to verify which serial port your uno is using and then enter that into the ide.
In Windows 10, Right-click the Start menu button and select Device Manager. With the Device manager open, connect the USB cable from the Uno to your computer. You will see a new line appear in the menu, Ports (COM & LPT). click on the little triangle next to it and you will see "Arduino Uno (COMx)" the "x" is the number of the COM port.
You then need to enter the device and port into the Arduino program ide that you are going to load . Select "Tools", then "Board" and click on "Arduino Uno" in the drop down menu. Then sect "Tools" again and select "Port", Click on the port in the drop down menu that your Uno is using.
When you have done that, the Arduino type and COM port number will be shown in the bottom green border in the ide. Then download the program.
Enter “uninstall program” in the Win10 search bar, read about uninstalling programs and follow the instructions.Thanks. Not sure how to uninstall and reinstall IDE
