Many tasks that can be performed on PC's these days require you to close all currently running programs. For example, almost every installer asks you to close all other applications to minimize conflicts and to avoid replacing in-use files. Other high-end tasks, such as burning CD's and defragmenting or scanning hard drives can slow down or even fail when other processes 'kick in', like background programs, the screen saver or a scheduled task.
Of course, you can manually Exit each program one by one, disable the screen saver… That is when SmartClose comes in! SmartClose will automatically close all running programs, disable the screen saver and halt all other processes that can interrupt without asking.
But what when you have finished the task that required you to use SmartClose and you want to restore the programs and such that were disabled by SmartClose? Restart the computer? No, because before SmartClose closes or disables anything, it will first save the current state of the system (running programs, screen saver…) to a 'system snapshot', that can later be opened and Restored again by SmartClose.
