How to Delete your entire Copilot conversation History
You delete your entire Copilot conversation history by accessing the Copilot settings page in your Microsoft account and clearing the chat data.
Copilot is Microsoft’s AI-powered assistant integrated into Windows 11 and other Microsoft products, designed to help you with tasks and answer questions. Clearing your conversation history removes all past interactions from your account, ensuring privacy and a clean slate.
Copilot chat logs are crucial for maintaining privacy and tidying AI interactions, especially after discussing sensitive topics. Since Copilot's Windows 11 integration began in late 2023, extensive chat logs can become hard to navigate.
Deleting Copilot conversation history gives users a fresh start. Removing old conversations lets users try new prompts and different ways of using Copilot. The older conversations will not affect Copilot's future replies, creating a clean slate for new interactions.
Sign in to your Microsoft Account privacy dashboard. Navigate to the “Copilot app activity history” section. Select “Delete all activity history” and confirm the permanent deletion of all your past Copilot conversations.
