Win 10 USB Driver for connecting to CH340 serial to USB chip

I am trying to connect to an Arduino with a CH340 serial to USB chip via my USB port but the computer will not recognize it. I am reading up that it requires a USB driver update for it to work.  However, I do not see anything that provides me with a driver for a Windows 10 PC that only has USB 3.0 ports.  Is there a Microsoft USB driver update that will enable connectivity to these boards?

Arduino Uno R3 ATmega328P CH340G board.


I think I just discovered the answer to my own problem based on your feedback.  While digging up the information for my response to your questions, I discovered the specific com port that Windows had assigned to the Arduino (USB-SERIAL CH340 (COM11)).  I selected that specific Com port in the Arduino program...and behold, it connected and is working just fine!

Thank you for your willingness to help - it turns out that Windows already had the driver installed and the error was prominently located somewhere between the keyboard and deskchair... :)
