my $xx=pack("LLLL",1,unpack("LL",$tr),0x02);
my $wa=pack("LLLL",0,0,0,0);
my $ui=length($wa);
my $sd=pack('L',0);

my $gcp=Win32::API->new("kernel32" ,"GetCurrentProcess"     ,[]       
+     ,'N');
my $opt=Win32::API->new("advapi32" ,"OpenProcessToken"      ,[N,N,N]

my $atp=Win32::API->new("advapi32" ,"AdjustTokenPrivileges" ,[N,N,P,N,
+P,N] ,'N');
my $lpv=Win32::API->new("advapi32" ,"LookupPrivilegValueA"  ,[P,P,P]

my $ewe=Win32::API->new("user32"   ,"ExitWindowsEx"         ,[N,N]    
+     ,'N');

my $gh=$gcp->Call();
my $wo=$opt->Call($gh,0x20||0x08,$op);
   $wo=$lpv->Call('',"SeShutdownPrivilege",$tr);
   $wo=$atp->Call($op,0,$xx,$ui,$wa,$sd);
