Use Win7 to develop ESP32, but it has not been able to solve the problem of USB records, that is, the USB Serial is always unable to install it. Although it can be used under Win10, it is also troublesome to switch the virtual machine to switch the virtual machine.

Frequent comparison of finding analysis, problem solving, smooth installation
