System Optimization & Registry Cleaning
Fine-tune your system with registry cleaning, startup management, debloating, and more.
Kudu includes a suite of optimization tools to help your system run faster and leaner.
Registry Cleaner
Scans the Windows registry for issues and safely fixes them.
Types of issues detected:
| Type | Description |
|---|---|
| Obsolete | References to software that's no longer installed |
| Invalid | Entries with malformed or corrupt data |
| Orphaned | Keys with no parent or associated software |
| Broken links | File paths pointing to locations that no longer exist |
| Vulnerability | Settings that may weaken system security |
| Privacy | Settings that could leak personal information |
| Performance | Entries that may slow down your system |
| Network | Network configuration problems |
| Service | Service-related registry issues |
| Task | Task Scheduler registry issues |
Each issue is assigned a risk level — Low, Medium, or High — so you can make informed decisions about what to fix.
Safety features:
- Original values are saved before any changes, so fixes can be rolled back
- Critical system keys are never modified
- You can review every issue before applying fixes
Startup Manager
Controls which applications launch when you log in.
Where it looks:
| Platform | Startup locations |
|---|---|
| Windows | Registry Run keys, Startup folder, Task Scheduler |
| macOS | Launch Agents |
| Linux | XDG autostart entries |
What you can do:
- View all startup items and where they come from
- Enable or disable individual items
- Remove startup entries entirely
- See boot time impact — Kudu analyzes boot trace data to show you how much each item slows down your startup (Windows)
Debloater
Identifies and removes pre-installed software you don't need.
Categories of bloatware detected:
| Category | Examples |
|---|---|
| Microsoft | Solitaire, Get Office, Mixed Reality, 3D Viewer |
| OEM | Manufacturer-bundled utilities |
| Gaming | Xbox app suite, Game Bar |
| Media | Groove Music, Movies & TV |
| Communication | Mail, People, Your Phone |
| Utility | Cortana, Maps, Weather, Tips |
Kudu uses safe removal methods to prevent system instability. On Windows, it removes apps through the Windows Package Manager (winget) or PowerShell. On Linux, it uses the appropriate package manager.
Service Manager
Manages system services with built-in safety intelligence.
Every service is classified using a knowledge base of 100+ services:
| Safety level | Meaning |
|---|---|
| Safe | Can be disabled without risk |
| Caution | May affect certain features — review before disabling |
| Unsafe | Critical system service — Kudu won't let you disable it |
Service categories include: Telemetry, Xbox, Print, Fax, Media, Network, Bluetooth, Remote Desktop, Hyper-V, Developer Tools, and more.
What you can do:
- Browse all services with their current status (Running or Stopped)
- Change start type: Automatic, Manual, or Disabled
- View dependency chains — see what each service depends on, and what depends on it
- Bulk optimize — disable all services marked "Safe" in a category with one click
- Kudu prevents you from disabling services that other critical services depend on
Uninstall Leftovers
Detects orphaned files and registry entries left behind after you uninstall a program.
- Scans common installation directories for folders belonging to programs that are no longer installed
- Identifies orphaned registry entries (Windows)
- Shows how much disk space you can recover
Network Cleanup
Cleans network-related caches and saved data.
| Target | What it does |
|---|---|
| DNS cache | Flushes the DNS resolver cache — useful when sites aren't loading correctly |
| Wi-Fi profiles | Removes saved wireless network profiles |
| ARP cache | Clears the Address Resolution Protocol cache |
| Network history | Removes network connection history |
Disk Repair
Detects and repairs corruption in Windows system files and disk structures. This tool combines several Windows repair utilities into a single guided workflow.
What it does:
| Step | Tool | Description |
|---|---|---|
| 1 | SFC (System File Checker) | Scans protected system files and replaces corrupted or missing files from the Windows component store |
| 2 | DISM (Deployment Image Servicing) | Repairs the Windows component store itself, which SFC relies on — fixes cases where SFC reports errors it cannot repair |
| 3 | CHKDSK (Check Disk) | Scans the file system for logical errors, bad sectors, and metadata inconsistencies on the target drive |
When to use it:
- Windows is showing unexplained errors, crashes, or blue screens
- System File Checker reports "found corrupt files but was unable to fix some of them"
- Applications fail to install or update with integrity errors
- After a power loss, forced shutdown, or failed Windows update
- Disk health warnings from S.M.A.R.T. monitoring
Safety features:
- Each step reports what it found before making changes
- SFC and DISM only replace files with known-good copies from the Windows component store
- CHKDSK runs in read-only mode first; write repairs require confirmation and a reboot
- Requires administrator privileges
Platform: Windows only.
Disk Analyzer
Visualizes how your disk space is being used with interactive treemap charts.
- See which folders and files are using the most space
- Drill into subdirectories for deeper analysis
- View file type distribution across each drive
- Analyze individual partitions separately
The treemap makes it easy to spot large files or folders you may have forgotten about.
