Q: Can I turn off the tap sound?
Yes, there are several registry keys that control the volume level of system sounds:
[HKEY_CURRENT_USER\ControlPanel\Volume]
"Key"=dword:10002 ; key clicks: 02 loud, 01 soft, 00 none
"Screen"=dword:10002 ; tap volume: 02 loud, 01 soft, 00 none
"Mute"=dword:7 ; 1=Notifications, 2=Apps, 4=Events, 7=Enable all sounds
"Volume"=dword:FFFFFFFF ; system volume 0 min, FFFFFFFF max
Note: For builds made before 2004, you'll have to change these keys programmatically, as the current CE loader doesn't support changing the HKEY_CURRENT_USER key.
