ScreenBackTracker

There are several ways to make a demonstration about involving an application on your PC, yet the easiest method is taking screenshots.
ScreenBackTracker is one of the nifty utilities you can rely on to perform this task since it continuously monitors your screen and takes snapshots.

Intuitive and user-friendly UI

The app comes with an intuitive user interface that makes it suitable for beginners and experts alike. Simply put, you only need to press a single mouse button to start the recording, then press it again when you want to stop it.
On the downside, you cannot schedule it to start automatically at a specified time or when a certain process is launched.

Generates a straightforward slideshow

When you stop the capturing process, you can take all the time you need to play the resulting slideshow and take notice of all the operations you performed. You can even adjust the level of zoom for each frame.
Unlike similar apps, the taken snapshots are not stored in a folder on your computer, so you cannot analyze them separately. The only way to examine them is via the previously mentioned slideshow.
You also need to keep in mind that ScreenBackTracker records the entire screen by default, meaning that you do not get the possibility to define a certain area of interest.

Automatically delete old snapshots

A handy feature of this application is the fact that you can set it to get rid of screenshots that were taken several hours or minutes ago.
All in all, ScreenBackTracker is a reliable utility for all those who want to capture their screen without too much hassle. More advanced users might not be too impressed with the limited feature-set, yet novices are bound to appreciate its minimalistic nature.
