Thank you very well. I just did that and it works. My next problem is when I set my source to tcp that is source s_tcp { tcp(ip(0.0.0.0) port(1468)); }; i'm not getting any log but it should listen to a remote host on port 1468. I tried it in another syslog-ng server running in cygwin and I get the log.
Here is my config:

#############################################################################
# Default syslog-ng.conf file which collects all local logs into a
# single file called /var/log/messages.
#

@version: 3.2
@include "scl.conf"

source s_local {
    system();
    internal();
};

source s_network {
    udp();
};

source s_tcp {
    tcp(ip(0.0.0.0) port(1468));
};

filter f_mail {
    host("192.168.10.60") and facility(17);
};

#filter f_sender {
#    match("SENDER");
#}

destination d_local {
    file("/var/log/essai");
};

destination d_user {
    usertty("*");
};

destination d_mysql {
    pipe("/tmp/mysql.pipe" template("INSERT INTO logs (host, facility, priority, level, tag, date, time, program, msg) VALUES ('$HOST', '$FACILITY', '$PRIORITY', '$LEVEL', '$TAG', '$YEAR-$MONTH-$DAY', '$HOUR:$MIN:$SEC', '$PROGRAM', '$MSG');\n") template-escape(yes));
};

log {
    source(s_tcp);

    # uncomment this line to open port 514 to receive messages
    #source(s_network);
    filter(f_mail);
    #filter(f_sender);
    destination(d_local);
    #destination(d_mysql);
};
