How to use Sony Xperia Throw to get display on windows PC (xperia C phone)

I have Sony Xperia C phone and I see throw feature in my phone in settings-> Xperia --> Throw settings. What I understand seeing videos online, throw feature allows you to share content of your phone on other device which supports it. I think PC is also supported because when I turn on PC, it shows it as available device in throw but now problem is that how to use it ?
Throw is connected with PC but how to use feature like show screen of phone on pc or play audio on pc ?

Does anyone knows here anything about it ?

As far as I know, to use throw feature, there must be throw compatible device like device with NFC support etc. I think PC can be used but I have no idea about it. Hopefully someone here can throw more light on it .
