I will show you how it looks in our device manager, task manager, and services panel. It's just the default executable included with the Quartus installation. We installed everything normally, including installing the JTAG drivers when prompted to by the main installer, and we haven't done anything involving windows services.
The VID/PID does indeed show up differently when it is showing as "Usb blaster variant" vs "Usb-BlasterII", specifically the "REV". And again, you can hear the windows device connect noise and see the device manage refresh when reopen Quartus Programmer after killing jtagserver.exe
