No sounds for logging in after intalling NIS 2010

Before installing NIS 2010, when Windows is waken up from Stand By, there will be a DINGDONG after I log in. But now this sound disappears with NIS2010 installed on the laptop. Log in sound from Start up, restart, log off is working fine.

 

I try to update NIS in the Desktop from 2007 to 2010 for comparison, the same problem appears. I remove NIS 2010 from laptop and reinstall it, nothing changes.

 

Seem that system default sound disappears after installing NIS is a usual problem since NPF + NAV 2001 + Win 98.  In previous version of this products, the "CLICK" for opening a folder will disappear after installing NIS for a while.

 

 

Windows XP SP3 + NIS 2010 ver.17.5.0.127
