Imagine, that your boss comes into your office when you are having a chat with your friend or reading news on the news site. What will be his reaction if he sees what you're doing? How do you think? And what happens with your career after that?
Do you like people who look from behind your back to your display and get information?
Are these well-known problems? How can you counteract them? We know a way out.
Use Window Magician!
It can hide windows, icons in the system tray, shut down applications or run your screensaver by pressing one hotkey. Then you can also restore the previous state of your screen.
If you leave you computer unattended, Window Magician can perform such actions by timeout and saves your information from the evil-wisher's view.
You can add the applications from the running processes or file on the disk to be hidden and change their behavior: to shut down, to hide their windows, to hide their system tray icons.
