This interface works great with both Windows 7 and 10, and you can plug both line-level devices and your guitars directly into it. The 48V phantom supply for microphones works great too. So, all in all, the hardware works great.
The ASIO drivers could use an upgrade, though. Input latency with Ableton Live is about 7 ms, and the output latency is about 30 ms, on a PC with an Intel i5 CPU. The ASIO configuration screen looks like something from Windows 3.1. It does not look good, but it works alright.
