H755 - STLink Virtual com port do not appear in Windows 10 Device Manager but it does on other Windows 11 machine

Hi, I'm currently working on a project with an H755 board.

The project uses UART communication. I'm developing it on a Windows 11 computer, and it generally works fine on that computer. So far, there are no issues.

However, after completing the project, I'd like to be able to use it on my older laptop (currently running Windows 10 with ESU). Here's the problem: my Windows 10 computer doesn't recognize the STLink virtual COM port. It only sees the device as a standard COM port with a Microsoft driver (not ST Microelectronics), and its UART communication then doesn't work.

I don't have CubeIDE installed on my laptop. I don't need it on this computer. Should I install the driver manually? If so, where can I find it? Any ideas on how to solve this problem?

Worth a shot:

STSW-LINK009 | Software - STMicroelectronics
