System Restore in Windows primarily restores system files and settings.

• A. System files and settings
• B. Personal documents
• C. Applications only
• D. User preferences only

Answer: (A)

System Restore is about returning Windows to a previous healthy state by reverting essential system components to how they were at a saved restore point. It targets system files, the Windows registry, and installed programs, so issues caused by updates or misconfigurations can be undone without affecting your personal data. This is why the best description is that it restores system files and settings.

Personal documents aren’t part of what System Restore changes, so your files in Documents, Desktop, Pictures, and similar folders remain as they are, unless you’ve manually moved or renamed them. Because of that, it isn’t just about applications, and it isn’t about user preferences alone—it's about the core Windows system components and program state.

If you need to recover lost documents, you’d use backups or features like File History or OneDrive.
