Simple utility to mute system microphone using C# and Powershell and show an on-screen notification. Does not require installing any additional packages.
You could create a shortcut to run the .js file and map a keyboard shortcut to it, but I have found that to be very slow to respond.
Instead, I have configured this to run in place of the "My Computer" shortcut and remapped my keyboard accordingly (QMK).
Something like the following regedit overwrites the "My Computer" shortcut:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\17] "ShellExecute"="wscript \"C:\\Users\\path\\to\\scripts\\MuteMic.js\""
