Hi all,
All I did was using audacity make a silent 1/2 second .wav file named it WindowsXPStart2.wav
Remember always copy the Wav files in different location for backup.
I made two .bat (batch files) using the move command moving the (clicking wav file) WindowsXPStart.wav to windowsxpstart3.wav next line move (silent wav file) C:\WINDOWS\Media\WindowsXPStart2.wav C:\WINDOWS\Media\WindowsXPStart.wav
move C:\WINDOWS\Media\WindowsXPStart.wav C:\WINDOWS\Media\WindowsXPStart3.wav
move C:\WINDOWS\Media\WindowsXPStart2.wav C:\WINDOWS\Media\WindowsXPStart.wav
Note: If you want to be more creative you could easily add another line to start nichehorde after you have moved to the silent wav
To return your clicking wav file just create a 2nd bat file to move the silent wav back to WindowsXPStart2.wav
and move the clicking wave back to WindowsXPStart.wav
move C:\WINDOWS\Media\WindowsXPStart.wav C:\WINDOWS\Media\WindowsXPStart2.wav
move C:\WINDOWS\Media\WindowsXPStart3.wav C:\WINDOWS\Media\WindowsXPStart.wav
Place the two bat (batch files) on your desktop click the correct bat file when needed.
Caution you don't want to click the wrong bat (batch) file or you will lose the clicking wav file.
Remember always copy the Wav files in different location for backup.
Dos is old but it still works.

Happy Niche finding
Mike
