Step 1. Open the Software and Perform a Full Scan
Open this PC cleaner, then run AI Mode for smart auto scanning or 1-Click Health Checker for a complete system check.
Click Scan to find junk files, registry errors, startup problems, privacy traces, and system vulnerabilities. Review the results and remove unnecessary items to enhance overall performance.

Step 2. Repair and Clean Up Detected System Issues
