Prevent the capture of your screen easily whenever you need to, with ScreenWings
ScreenWings is a free and simple utility that lets you avoid screen capture if you are suspicious that some screen capture utility can do this without your consent.
When you activate ScreenWings, which is as simple as pressing a button, all screen capture utilities will get a black screen whenever they try to capture your screen.
To disable the blocking of screen capture utilities just press again the same button.
ScreenWings prevents also the official PrintScreen or any screen capturing utilities created by Microsoft itself. This is good news, since malware can exploit the official methods to take screenshots.
