PC-Clean: Ultimate Guide to Optimizing Your Windows PC

How to Use PC-Clean to Speed Up Your Computer — Step-by-step

Before you start

• Backup: Create a full backup of important files (external drive or cloud).
• Restore point: In Windows, create a System Restore point.

1. Install and update

1. Download PC-Clean from the official vendor site and run the installer as Administrator.
2. Launch PC-Clean and let it update its definitions/components.

2. Run an initial scan

1. Open the app and choose the full/junk scan (not just quick).
2. Let the scan finish; review the summary of issues (junk files, browser cache, leftover installers, invalid shortcuts, registry entries, startup items).

3. Review results and uncheck anything important

• Carefully inspect large files and detected programs.
• Uncheck items you recognize as needed (personal files, important browser data, or apps you want to keep).

4. Clean junk files and browser data

1. Select “Remove junk” / “Clean” for temporary files, caches, and browser data.
2. Confirm and let PC-Clean delete selected items.
3. Restart the PC if prompted.

5. Disable or remove unwanted startup items

1. Open PC-Clean’s Startup Manager (or Tools → Startup).
2. Disable nonessential programs (games updaters, cloud clients you don’t use, bloatware).
3. Leave security software and drivers enabled.

6. Uninstall large or unused programs

1. Use PC-Clean’s Uninstaller module (or Programs → Uninstall).
2. Sort by size or last used; uninstall apps you don’t need.
3. Use the app’s “scan for leftovers”
