Hello gang, using some CH340N in a project would love to find a way to change the IDENTIFICATION that Windows10 comes up with in Device Manager to my product name!
Saw some app for CH340B called CH340BConfirg.exe was I think the right Ideal but did not work with CH340N.
Saw some Chinese app called CH340CFG.exe that also looked good but could not find a working site where I could download it all in Chinese!
Any suggestions! Please ! Help!

The reason why there is a utility for the CH340B is that that chip has an EEPROM that can store information; see the datasheet.
You can modify the registry; see e.g. https://www.eightforums.com/threads/tutorial-how-to-change-device-names-in-device-manager.15321/.
Well, respectfully, I would not change the registry as it is a local-PC change and as a "product" you only get the glory on you own PC ... everyone else gets the manufacturer's enumeration.
The "right way to do this" is to get your own VID/PID but that is often too expensive for one-off units.
Changing the chip eeprom is often complicated as you have found out as the utilities are chip-version-centric.
This is the manufacturer's English webpage if you have not already found it:

If you are making a product here , then you would be better off using a processor on a PCB than using an Arduino
You can then buy the chip to do the UART TO USB part, these have facility to set a device name in them .
