Local Copilot Memory via Dynamic BitLocker Partition on Windows

📋 Details

Hello Microsoft team,

I’d like to propose a feature that could significantly enhance privacy, continuity, and personalization for Copilot users on Windows: a local memory system stored in a dynamically sized BitLocker-encrypted partition.

🔐 Concept Overview

Create a dedicated partition on the user's PC (e.g., CopilotVault) that stores:

• Compressed summaries of past conversations
• User preferences and creative assets
• Project context and semantic snapshots

This partition would be:

• Encrypted via BitLocker
• Dynamically resizable based on usage
• Accessible only by Copilot and the user, with key management via TPM or user authentication

🧠 Benefits

• Privacy-first: All memory is stored locally, not in the cloud
• Continuity: Copilot can recall long-term context across sessions
• Security: BitLocker ensures data protection even on shared or enterprise devices
• User control: Users can view, purge, or export their Copilot memory

⚙️ Technical Suggestions

• Use vector-based compression (e.g., semantic clustering) to store memory efficiently
• Enable dashboard access for users to manage their CopilotVault
• Integrate with Feedback Hub or Microsoft Account for optional sync across devices

This feature would empower users with secure, intelligent, and persistent AI memory — especially valuable for professionals, educators, and developers working on long-term projects.

Thank you for considering this idea. I’d be happy to elaborate or collaborate on a prototype concept.

Best regards, Laurent📋 Details
