This is necessary for an audio driver defaulty installed on most windows machines.
My skype for windows gives a warning related to privacy when i begin a call. Although i am easilya able to dismiss it, i am concerned about the problem.

Win 8 --- using Business Skype --- this launches a 3rd process that runs away with CPU!
  Mike Cooper  
It takes too much CPU %. Not good at all....
It's using 25% CPU. I would like to get rid of it.

I watched Windows 10 Performance Monitor while accepting this API in Skype and the difference is little to none. Memory 0.7 MB, CPU 0%, with Skype running idle.
I believe it is Realtek, but have not figured out why Skype puts up a message about it. None of my AV or Malware scans complain about it.
    (further information)
showed up under application tools ; Manage along with numerous things that look suspicious. I try to uninstall and comes back.
It is not dangerous and is important to audio processing while watching or listening to media.
Based on what I read, it is NOT needed and therefore I did not install it as suggested by Skype.
Seems to be fine and is needed to play sounds and stuff.
I use Windows 8.1 & it's software for better sound experience.
