Tixati 3.42 was set auto start on win 10, but it can't auto shutdown after finishing all download, RSS has set not auto download. I have to shutdown win 10 manually. when I restart win 10, tixati 3.42 auto shutdown after 60 seconds.

Do you have it set to close the program or shutdown your computer?
Are you sure all downloads are complete?
What is the delay set to?
How long are you waiting after all your downloads complete to force shutdown?
Do you have the 'persist after restart' option checked on?
It might be shutting down after the restart because all your downloads are complete.
