Computer Hacking Forensic Investigator (CHFI) Practice Exam

The RunMRU key is the correct choice because it specifically stores the Most Recently Used (MRU) list of commands that have been executed through the Run dialog box in the Windows operating system. When a user types a command into the Run box and executes it, that command is recorded within this registry key, allowing investigators to uncover what programs or paths a user has recently accessed.

This information can be crucial in forensic investigations as it provides insights into user activity and can help establish patterns of behavior or intent.

In contrast, the UserAssist key tracks applications that users have executed but does not specifically focus on the Run dialog entries. The MountedDevices key is related to devices that have been connected to the computer, not user activity through the Run command. The TypedURLs key tracks URLs entered into browsers, hence it is irrelevant when searching for commands used in the Run box. Understanding the specific purpose of these registry keys helps forensic analysts extract pertinent information during an investigation.
