What is the purpose of the System Restore feature in Windows?

The System Restore feature in Windows is designed to revert the system to a previous state to recover from issues. This functionality allows users to restore their computer's settings, files, and system configurations to an earlier point in time, which can be particularly useful after experiencing problems such as a software installation that caused instability, malware infections, or other system malfunctions.

When System Restore is used, it can roll back changes made to the operating system files, installed applications, registry settings, and sometimes even hardware configurations. This is achieved by utilizing restore points, which are snapshots of the system's state taken at various times. By selecting a restore point from a time prior to the issue, users can effectively undo the changes that led to the current problems without losing personal files.

The other options do not align with the purpose of System Restore: deleting temporary files is related to disk cleanup and optimization, creating new user accounts pertains to user management, and upgrading the operating system deals with moving to a newer version of the software. Each of these serves a different function and does not involve reverting system configurations or restoring stability, which is the core functionality of System Restore.
