Thanks for answering.
No the sensitivity of microphone has not changed.
As I hope I mentioned, before the latest Windows, and my screen reader, Jaws, updated, within the last 2 weeks, When using Skype, meaning having it on, and having another window open, if I was talking with you, there was a setting that if made, you could not hear what was going on in that second window. Again, meaning, If I were playing poker in another window you could not hear it.
Right now, you hear everything coming from my screen reader and keystrokes. Not good. Not this way before.
