What is the primary usage of a restore point in Windows?

A restore point in Windows is primarily used to roll back system changes. When a restore point is created, it captures the current state of system files and settings, allowing the user to revert the system back to that specific point in time. This can be particularly useful after installing an application, driver, or Windows update that causes instability or other issues. By restoring the system to a previous state, users can effectively undo any problematic changes and restore normal operation.

The other options do not accurately reflect the primary purpose of restore points. Fixing hardware problems typically requires physical repairs or adjustments, not software restoration. Clearing temporary files is a maintenance task aimed at freeing up storage space and improving performance but is unrelated to restore points. Upgrading system firmware pertains to hardware-level updates and does not involve rolling back or restoring software settings and configurations.
