If one of the updates of Windows 10 made your Com port(s) go away, here’s the solution.
- Open “Device Manager“
- Select menu “Action” -> “Add legacy hardware“, then Click “Next“
- Select “Install the hardware that I manually select from a list (Advanced)” -> then click “Next“
- Scroll down, then select “Ports (COM & LPT)“, then click “Next“
- Select “Manufacturer” as your need, (in this case, I’m selecting standard type or default option) then click “Next“
- Finish!
