But this also is a real turn-off, the shutdown of the sound file is damaged. To this, experts advise you can enter the Control Panel, open the "sounds and audio devices", switch to the "voice" label, and then set the "sound scheme" set to "silent" or "program" in the "exit Windows" sound is set to "no".

Then you will need to check whether there are other resident program was not closed. You can open the Task Manager, in the "process" tab to see what is the application process, it can be forced to shut down, or you can hold down the CTRL key, and then click the "task manager" "shutdown" menu to "shutdown" command.
