Ok, I have explored into the sound and mic setting menus and found that mic vol level is @ 0, turning it back to 100 and opening skype results in mic vol level going back to 0 with the windows sound mic settings and skype open simultaneously.
Right, I have ventured into Windows 10 Privacy - Microphone Settings and found that Host Process (Rundll32) way at the bottom of the screen was not being utilized when skype was open and this muting problem was occurring.
Skype must have gone corrupt, because the mic was working (tested by mic volume input level detector in control panel sound settings) but Skype disabled the mic time and time again, I uninstalled Skype and went to the windows store and redownloaded Skype made the installation, restarted the pc and now the mic is working again as it should.
