Processes and Windows History (Pro edition)

EndTask can log Processes and Windows that are just loaded or terminated.

To start logging : Click ‘Start’ in Logs dropdown menu in General functions Toolbar at the top of Main Window , or click 'Start' button in Mini Tools window

EndTask will log new Processes and Windows and that which is about to close. 

You can click ‘Pause’ under ‘Start’ item to pause logging, or you can click ‘Stop’ under ‘Pause’ item to stop logging completely. 
To know whether EndTask is logging or not, watch Status text in Mini Tools.

To view what EndTask logged, go to Logs window and make sure  "Task History" is selected, you can find Logged data at the last section of Logged Data.  (For more information on reading Logged data see Logs )  

You can also specify the timer of the logging process (for instance: 2 seconds means that EndTask will take a snapshot of the running tasks every 2 seconds). The less this interval is, the more accurate the logging process is, yet the more slower your computer may be. (more information is given in the ‘General’ tab in Options)
