Automatic Repair Explained (Complete Breakdown)
Let’s take a deeper look at how Automatic Repair works.
When you click Run Automatic Repair, RepairKit will:
- Create a System Restore Point
This is a safety checkpoint. If you don’t like any changes, you can roll back instantly using Windows Restore. - Apply System Policies
These include:- Fixing broken Explorer options
- Repairing missing settings

These are performance-oriented tweaks such as:- Improving responsiveness
- Removing outdated policies
- Fixing sluggish UI behaviors
- Apply System Tweaks
These target:- Windows animations

- Memory management
- File handling
- Feature Tweaks
These may include:- Disabling unnecessary built-in Windows components

These reduce background load by disabling unused Windows services. - Remove Bloatware
This includes uninstalling apps like:- Clipchamp
- 3D Builder
- Bing Weather

- Microsoft To Do
- Copilot (if installed)
- Any preloaded system apps marked as bloatware
- Scan for Malware
Using portable scanners integrated into RepairKit. - Update Outdated Programs
If any installed software requires updates, RepairKit notifies you.
Within about a minute, the tool completes everything and shows:
“Automatic repairs completed.”
Your system now runs lighter, cleaner, and faster.
Understanding the Config Folder (For Advanced Users)
If you’re curious about what each tweak does, RepairKit gives you full transparency.
Inside the extracted RepairKit folder:
- Open the config folder.
- You’ll see multiple JSON files such as:
- policies.json
- registry.json
- bloatware.json
- services.json
- features.json
You can open any JSON file in Notepad to see:
- Which registry entries will be modified
- Which Windows apps will be removed
- Which settings will be applied
- What services will be disabled
This level of transparency makes the tool safe and user-controlled.
Useful Programs: A Complete Tool Hub
RepairKit includes a section called Useful Programs, which acts like a ready-to-run toolbox.
You don’t have to download or install anything manually—just click Launch next to any program.
Some included utilities:

- Autoruns – view startup programs
- Process Explorer – advanced task manager
- Emsisoft Emergency Kit – malware scanner

For example:
If you click Launch CPU-Z, the app instantly opens and shows:
- CPU model
- Core speed
- Motherboard details

Similarly, clicking Launch Emsisoft gives you a full portable malware scan without installing antivirus software.
System Shortcuts: Quick Access to Hidden Windows Settings

RepairKit solves this by giving direct buttons to access:
- Display settings

Just click and the setting window opens instantly.
This is especially useful for beginners or anyone who doesn’t want to search through menus.
