device manager drivers/update/fix help

I need help with my drivers as they aren't showing up right in Device manager. I have double or triple entries in some of the categories; I have provided a link or file so that you can see what mine looks like. If anyone could direct me in the right path that would be awesome! I think the reason for my mouse studders/issues and also performance issues in the many games that I play is the reason behind these Drivers. Below is a image that I captured with gyazo that lists my devices.

-BenQ XL2420Z 144hz
-Logitech G403 Prodigy
-Corsair Vengeance K95

-When I fix the drivers that I need will the grayed out devices fix themselves/disappear in Device manager? Also, if/when I get my drivers all squared away and updated.. let's say I have some grayed out devices that are still in those sections.. is it OK to uninstall those or not?

-I also don't have any idea what those Microsoft streaming devices in Sound are!??! Could it be something I need to turn off in BIOS or?

-Lastly, what's the deal with the WAN Miniports?


Thank-you!
