Configure Windows key + C or the Copilot key to launch the full Copilot application instead of Quick View: open Copilot, then go to Account > Settings > Copilot Keyboard Shortcuts and select the full-application behavior.^1^
After that, pressing the configured key is the available one-step route to a dedicated, resizable Copilot window. The Windows Copilot app behaves like a normal Windows app: it can be moved, resized, maximized, switched to with Alt+Tab, and should reopen in its previous state.^2^
Sign-in limitation
There are two different experiences:
- Windows Copilot app: A personal Windows app session requires a Microsoft account.^3^
- Free web Copilot: Sign-in is not required for basic AI chat. Signing in adds features such as chat history, image creation, longer conversations, and voice interactions.^4^
Therefore, the closest supported choices are:
- One-step full Windows app: Configure the keyboard shortcut, with Microsoft-account sign-in.
- No Copilot sign-in: Open
https://copilot.cloud.microsoftin a browser and use the free experience. This does not restore the former panel-to-full-page button.
Request restoration of the button
No documented setting currently restores the previous expand/open button inside the panel. Submit it as a feature request:
- Press Windows key + F to open Feedback Hub.
- Select Suggest a feature.
- Use a specific title such as:
Restore one-click “Open in full window” button in Copilot Quick View - Explain that the button should open the existing conversation in the full Copilot window without introducing an additional sign-in prompt.
- Search for an existing matching suggestion and Upvote it, or submit a new one.
Feedback Hub accepts new feedback without signing in, although signing in is required to search existing feedback and track its status.^5^
