CCleaner shows you exactly what was cleaned, how much space was freed, and how many startup programs were optimized.

How to Safely Use the Registry Cleaner
⚠️ Important Warning
The registry cleaner can potentially cause problems if used incorrectly. Most users don't need to clean the registry. Only proceed if you're experiencing specific issues.
Always create a backup before cleaning the registry!
Create a System Restore Point
Before cleaning the registry, create a restore point:
- • Open Start menu, type 'Create a restore point'
- • Click 'Create' button
- • Name it 'Before CCleaner Registry Clean'
- • Wait for Windows to create the restore point
Open Registry Cleaner
In CCleaner, click 'Registry' in the left sidebar. You'll see various registry issue types checked by default.
Scan for Issues
Click 'Scan for Issues'. CCleaner will search for registry problems. This typically finds 100-500 issues (this is normal!).
Save a Backup
Click 'Fix selected issues'. CCleaner will ask to save a backup. ALWAYS click 'Yes' and save the backup file.
- • Save to Documents\CCleaner
- • The backup file is named with date/time
- • You can restore this if something goes wrong
Fix Issues
Click 'Fix All Selected Issues'. CCleaner will clean the registry entries.
Restart Your Computer
After registry cleaning, restart your PC to ensure changes take effect properly.
How to Restore Registry Backup
If something goes wrong after registry cleaning:
- 1. Navigate to Documents → CCleaner folder
- 2. Find the most recent .reg file
- 3. Double-click it and confirm you want to add it to registry
- 4. Restart your computer
How to Manage Startup Programs to Speed Up Your PC
Startup programs can significantly slow down your boot time. Here's how to manage them with CCleaner:
Open Startup Manager
Click 'Tools' in the left sidebar, then select 'Startup'. You'll see all programs that launch when Windows starts.
💡 High impact on boot speed
Identify Unnecessary Programs
Look for programs you don't need immediately at startup. Common culprits:
Common examples:
- • iTunes Helper
- • Adobe updaters
- • Spotify
- • Discord
- • Steam
- • Manufacturer bloatware
Disable Programs
Select a program and click 'Disable'. This prevents it from starting automatically, but you can still open it manually when needed.
💡 Programs can still be launched manually
Check Other Startup Locations
Use the tabs at the top to check 'Windows', 'Scheduled Tasks', and 'Context Menu' for additional startup items.
💡 Be cautious with system processes
Test Your Changes
Restart your computer and time the boot process. You should notice a significant improvement!
💡 Typical improvement: 10-30 seconds faster
⚠️ Programs to Keep Enabled
- ✅ Antivirus software (Windows Defender, etc.)
- ✅ Graphics card control panels (NVIDIA, AMD)
- ✅ Essential hardware drivers
- ✅ Cloud storage sync (if you use it actively)
- ✅ VPN software (if you need it at startup)
How to Use the Disk Analyzer to Free Up Space
Access Disk Analyzer
Click 'Tools' in the left sidebar, then select 'Disk Analyzer'. This tool helps you visualize what's taking up space on your drives.
Select a Drive
Choose which drive to analyze (usually C:). Click 'Analyze' and wait for the scan to complete (can take 1-5 minutes).
Review the Results
You'll see a pie chart showing file types and their sizes. Common space hogs include videos, games, photos, and temporary files.
Drill Down
Click on any segment to see which folders contain those files. Navigate through the folder tree to find large files.
Take Action
Once you've identified large unnecessary files, you can delete them directly or use Windows File Explorer to manage them.
Common Space-Wasting Folders
- 📁 Downloads Folder: Old files you no longer need
- 📁 Windows.old: Previous Windows installation (can be 10-30 GB)
- 📁 AppData\\Local\\Temp: Temporary files
- 📁 Windows\\SoftwareDistribution: Windows Update files
- 📁 Steam/Games: Old games you don't play
