AutocreenShot is essentially like a digital camera for the screen of your computer. This application will log what is displayed on your screen. Very handy if you want to monitor what is going on your screen when you are out (ex: parental control).
To use this application just download it and run it from your start menu. It will take a snapshot of your desktop at the current time (or the time when you logged into Windows). If you want you can also save the screen shots to your hard drive and have an image of your desktop that you can then edit. When you are done editing just save the file as an image file and you are ready to make the changes you need.
The free version has limited functionality. You can only see the first 100 screens. There are many screen shots available for free at the official website but they do not always show the screen shot in its true color or resolution. In order to see the full picture, download autoscreenshot 1.0.5.10 full version. It has all the same functions as the free download but provides better quality and resolution.
