The program runs the build Service_test.exe, enters the console with the administrator, CD C:\Windows\system32 then uses the Sc.exe tool SC create service_test binpath= D:\TEST\ Service_test.exe the console will print out CreateService success. Enter service management to manually open the service at this time
