There is a way to review the log of the historical activities on your computer. That can be useful, if you want to track the chain of events that lead to the certain problems with computer performance, or you need to check what computer-related activities on your PC at your absence were performed.
First, you should go and enter the following command in the Command Prompt: "Start > Run > Eventvwr.msc".
Note that all events are recorded in three stored log files: Application, Security, and System. These logs can be reviewed and archived for future use. For our current purposes, we will use the System log.
Click on “System" in the left-hand column for a list of events. Look for a date and time of the data you want to check, or when you were not at home. Double click on the info and it will show you the related details. You can also use this log file to check for how long your computer was used in your absence. Just look at the time the computer was turned on and off for that day of question.
