Multiple devices loading on COM1 and device manager crashes on changes

Question

I am using multiple Arduino Unos (by Elegoo). They are all loading on COM1. That is, i attach 3 Arduinos via USB, and in the Device Manager they all show up as "Arduino Uno".

When I go to the port settings, and try to change the port to a higher number, when i click ok, device manager crashes (exits unexpectedly).

I had it search for the latest drivers, and they are all up to date.

Hello @Cosmo22

There are manu reasons why the MSC console can crash, but as a workaround I can recommend you setting the port via registry on the path HKLM\Current Control Set\enum\usb\<device>\Device Parameters\PortName

Reference: https://learn.microsoft.com/en-us/windows-hardware/drivers/serports/registry-settings-for-a-plug-and-play-serial-device

Otherwise, the general recomendation would be to ensure that your system is fully updated and perform a DISM Windows repair: https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/repair-a-windows-image

Hope this helps with your query,

Thanks, I ran the DISM Windows Scanhealth:
C:\Dism /Online /Cleanup-Image /ScanHealth

Result: "No component store corruption detected."
