I occasionally make short recordings of what's on my screen - the monitor, not the screens on my windows. Occasionally, it's not possible to record from the screen. It's somehow possible to block users from recording screen content. I tried four different programs, and I got sound and a black screen.
If I was desperate, I could use a camera to record the screen, but I'm not desperate. I wonder how they prevent recording.
Short answer is it's not possible to prevent recording what's on your screen. It can be made a bit difficult and stop cursory recordings with HTML/Java code but those wanting badly enough can always record no matter what. Personally, I've rarely encountered this and if I did, I wouldn't likely be bothered to circumvent the hiding HTML code.
