Windows 10: How to fix my microphonebuilt in on my laptop.

When Im talking about my microphone I don't mean the microphones you plug into your computer I mean the built in ones. My microphone on my laptop seems to not work. I have watched alot of youtube videos on how to fix it however none have worked. How could I fix this?

I'm online from my wifi laptop but can't connect to my home network

Nope, I've tried all the steps of all the fixes listed by Dalchina and Try3 but the problem still exists. The W10 laptop refuses to access my main W7 pc (named CG16) on my home network, although it can 'see' it, ie, it shows CG16 in the network list.
The only thing I haven't tried is Dalchina's suggestion about creating a shortcut, mainly because I'm not sure where this shortcut is supposed to be. I'm assuming it has to be on the W10 laptop but I don't understand how it could work. More info please, Dalchina, if you'd be so kind.

Daymin, sorry: I have no idea what you're trying to say.
