TPPrev,
TP : TTokenPrivileges;
Token : THandle;
dwRetLen : DWord;
begin
Result := False;
OpenProcessToken(GetCurrentProcess,TOKEN_ADJUST_PRIVILEGES
or TOKEN_QUERY, @Token );
TP.PrivilegeCount := 1;
if( LookupPrivilegeValue(nil, PChar( aPrivilegeName ),
TP.Privileges[ 0 ].LUID ) ) then
begin
if( aEnabled )then
TP.Privileges[0].Attributes:= SE_PRIVILEGE_ENABLED;
else
TP.Privileges[0].Attributes:= 0;
dwRetLen := 0;
Result := AdjustTokenPrivileges(Token,False,TP,
SizeOf( TPPrev ),
TPPrev,dwRetLen );
end;
CloseHandle( Token );
end;
function WinExit( iFlags : integer ) : boolean;
// possible Flags:
// EWX_LOGOFF
// EWX_REBOOT
// EWX_SHUTDOWN
begin
Result := True;
if( SetPrivilege( 'SeShutdownPrivilege', true ) ) then
begin
if( not ExitWindowsEx( iFlags, 0 ) )then
