Set the value of adding system environment variable _NT_SYMBOL_PATH to: srv*c:\symbols*http://msdl.microsoft.com/download/symbols
In this way, when WinDbg is started, it will automatically find this variable, and then go to the corresponding url address to download the symbol file of the corresponding system, and save the downloaded symbol file in the C:/symbols path. This path will be created by itself. Of course, you can change the path according to your needs
