Silent Screen is a more powerful application to make screenshots than just using the Print Screen button.
It is a program that works in the background, on the Windows taskbar. From there you can change the adjustments like the password protection, define a route to save the screenshots, the times they are to be done, or automatic updates. You can capture the activity of your PC even when you have deleted the browser history.
One advantage of Silent Screen is that it is continually updating itself thanks to ideas and suggestions of the users themselves. It is completely free and has a large community of anonymous collaborators on the webpage.
NOTE: For Silent Screen to work correctly you need
Microsoft .NET Framework installed in your PC.
