Microsoft 365 Copilot Performance optimization and feature requests for Copilot Desktop

Question

Hey Microsoft, we need to talk about the Copilot Desktop app. Right now, it is incredibly sluggish even on a PC with 16GB of RAM. You have the best engineers in the world; I know you guys can make this thing as fast and snappy as Notepad!

Also, could we please get some better chat management? It is super frustrating having to dig through my history to find critical conversations. We desperately need the ability to pin and group chats (similar to Claude Projects).

Forcing us to use Notebooks for this doesn't work because Notebooks don't have internet access. We need to be able to organize our chats while still interacting with the web and our work data!

Answer 1

Performance and feature behavior for the Microsoft 365 Copilot app and Copilot Chat are defined by the current product design and recent updates.

For performance and responsiveness:

• Microsoft 365 Copilot Chat now runs on GPT-5 by default across Android, Windows, iOS, Mac, and Web. Copilot automatically routes prompts to the best-performing models for each task, using fast models for basic tasks and specialized reasoning models for multi-step requests. This is intended to deliver faster, higher-quality results and reduce friction in everyday use.
• The Microsoft 365 Copilot app and Copilot Chat experiences are grounded in work data and web data (for users signed in with Microsoft Entra accounts) and are covered by enterprise data protection, which adds security and compliance controls but can also influence how data is processed and retrieved.

For chat management and organization:

• Microsoft 365 Copilot Chat has introduced a redesigned navigation pane with expanded chat history on Windows and Web. This makes it easier to switch between conversations and pick up where work was left off, particularly for fast-paced projects and multitasking.
• The context provided does not describe pinning or grouping chats (similar to “projects”) as an available feature in Copilot Chat. Current improvements focus on navigation and history rather than user-defined pin/group structures.

For web and work-data access vs. notebooks:

• Microsoft 365 Copilot Chat’s web scope is available at no additional cost for users signed in with a Microsoft Entra work or school account. This experience grounds conversations in web data and work data, and is covered by enterprise data protection.
• The context does not describe notebooks or their connectivity model, so no additional behavior can be confirmed from the provided information.

For feedback and feature requests:

• The documents focus on current capabilities (GPT-5 default model, expanded history/navigation, voice input, enterprise data protection) and do not specify a direct feedback channel in this context. However, feature requests such as performance improvements, pinning/grouping chats, or changes to notebook behavior would need to be submitted through Microsoft’s standard feedback mechanisms (for example, in-product feedback or admin channels) outside the scope of this content.
