The system beep (pc speaker) from WinXP running under VMware was driving me crazy as I have sound disabled on my virtual machines.
Easy fix from cmd within Win XP:
sc config beep start= disabled
赤信号皆で渡れば怖くない | If everyone crosses against the red light, then there’s nothing to be afraid of.
Alternatively you can set mks.noBeep = “TRUE” to your .vmx file or ~/.vmware/preferences files (this works on all virtual machines, not just windows ones *eyes netware*).
