Windows 11 Start Menu Categories: Local JSON, Privacy, and Customization Limits

Windows 11's Start menu has undergone another evolution, this time introducing a categorization system powered by local JSON files rather than cloud-based intelligence. This subtle but significant change represents Microsoft's attempt to balance user privacy with organizational functionality, while also raising questions about customization limitations and future scalability.

How Windows 11's New Start Menu Categories Work

The latest Start menu update uses a local JSON database stored at %LocalAppData%\Packages\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy\LocalState\AppCategories to define application groupings. This file contains category definitions that map Microsoft Store apps to predefined groups like "Productivity," "Creativity," or "Entertainment."

Key technical aspects:
- Local processing: All categorization occurs on-device
- JSON structure: Simple key-value pairs linking app IDs to categories
- Update mechanism: Modified through Windows Update rather than real-time cloud sync
- Default categories: 12 predefined groups covering common app types

The Privacy Advantage of Local Categorization

Microsoft's decision to use local JSON files instead of cloud-based categorization addresses growing privacy concerns:

• No usage tracking: Unlike previous implementations, this system doesn't require sending app usage data to Microsoft servers
• Reduced telemetry: Category assignments don't depend on behavioral analytics
• Offline functionality: Works without internet connectivity

"This represents a meaningful shift toward on-device intelligence," notes UI/UX expert Dr. Elena Petrov. "By keeping the categorization logic local, Microsoft reduces potential privacy vulnerabilities while maintaining organizational benefits."

Limitations and User Frustrations

While the local JSON approach has advantages, users have identified several constraints:

1. Limited customization: Users can't easily create or modify categories
2. Store app focus: Primarily affects Microsoft Store apps rather than all installed programs
3. Update dependency: Category changes require full system updates
4. Inconsistent coverage: Many common apps remain uncategorized

Power users have discovered workarounds by manually editing the JSON file, but these modifications get overwritten during system updates.

Technical Deep Dive: The JSON Structure

A sample from the categories JSON file reveals the straightforward structure:

{
  "9WZDNCRFJ3P2": "Productivity",
  "9WZDNCRFJ3J1": "Entertainment",
  "9WZDNCRFHVQM": "Utilities"
}

Each entry pairs a Microsoft Store app ID with one of the predefined categories. The system appears to use these mappings exclusively rather than employing any machine learning or heuristic analysis.

Comparison to Previous Start Menu Versions

Future Development Possibilities

Microsoft could expand this system in several directions:

• User-editable categories: Allowing custom groups without JSON editing
• Win32 app inclusion: Expanding beyond Store apps
• Dynamic updates: More frequent category refreshes
• AI-assisted organization: Optional cloud-enhanced sorting

However, the current implementation suggests Microsoft prioritizes stability and privacy over advanced features.

User Workarounds and Third-Party Solutions

While Microsoft limits official customization, alternatives exist:

• Start11 (Stardock): Offers complete Start menu reorganization
• ExplorerPatcher: Restores Windows 10-style grouping
• Manual JSON edits: Temporary customization between updates

These solutions demonstrate user demand for more flexible app organization.

The Bigger Picture: Microsoft's Design Philosophy

This change reflects Microsoft's evolving Windows 11 philosophy:

• Privacy-first: Reducing cloud dependence where possible
• Consistency over customization: Standardized experiences
• Gradual evolution: Incremental rather than revolutionary changes

While some users lament lost flexibility, others appreciate the increased privacy and simplified interface.

Expert Recommendations

For different user types:

• Casual users: Accept default categories as-is
• Power users: Explore third-party tools for deeper customization
• Enterprise IT: Group Policy can disable categories entirely
• Privacy-focused users: This implementation is currently the most private option

As Windows 11 continues evolving, the Start menu's balancing act between organization, privacy, and customization will remain a key area to watch.

Final Thoughts

Windows 11's JSON-powered Start menu categories represent an interesting middle ground in modern OS design. By choosing local processing over cloud intelligence, Microsoft addresses privacy concerns while delivering basic organizational functionality. However, the implementation's limitations highlight ongoing tensions between user customization desires and Microsoft's vision for a streamlined Windows experience. As the system matures, users hope for more flexible categorization options that maintain the current privacy advantages.
