WMI - SecurityCenter/AntiSpywareProduct won't update on VistaSP1   

On Vista (without SP1), if user turn off the AntiSpyware such as Defender, 
the WMI class AntiSpywareProduct (root\SecurityCenter) will show product 
disabled.
But after SP1 is installed, the status won't change according tothe user's 
setting. 

Please help.
Thanks
