Best answer I found in google. It was "You may want to access the Task Manager, by Right Clicking on the Status Bar on the bottom of your screen.Then Left Click on the Task Manager. Click on "Applications", highlight -all- the active items listed, and click "End Task". Wait for the process to finish, and click "End Task" on any warning windows that come up. When the Applications section is empty, click on EXIT. You can then proceed with Shut-Down".
Thank you!
