system still sends ping after set outbound traffic to block

hi friends

i win 2008 R2 , i found that when i set firewall state outbound traffic status to block (in All 3 profiles including domain, public, private), still system can ping other systems (although even there is no ICMPv4 echo request Allow rule).

where from this setting is applied? where from can we change this exception so that also ping (outbound ICMPv4 echo request) be blocked.

thanks in advanced
