Hi TH,
Thank you for sharing your detailed experience and concerns regarding the recent changes to the Windows 11 Copilot desktop app sign-in options.
To clarify, the web version of Copilot continues to support Google sign-ins. Unfortunately, Microsoft has not yet provided public communication explaining why this disparity exists or if and when Google sign-in support will return to the desktop app.
We understand that this change disrupts workflows, especially for users relying on memory continuity tied to Google accounts and the integrated Copilot hardware key functionality. Currently, the only fully supported sign-in method for the desktop app is a Microsoft account. When the same email is used for both Google and Microsoft accounts, they are treated as separate identities by the app, which can affect access to stored data and memory continuity.
While no official timeline or roadmap has been announced regarding restoring Google sign-in on desktop, or clarifying the fate of data linked to Google accounts within the app, we recommend using Microsoft account sign-in on the desktop app for seamless functionality.
Your workaround with AutoHotKey scripts to access the web version is a practical interim approach. Your feedback on the silent removal and impact on workflow is valuable, and it is encouraged to submit feedback through the official Microsoft feedback channels to help influence future updates. You can use Window + F to send your feedback. You can refer to: Send feedback to Microsoft with the Feedback Hub app - Microsoft Support.
Thank you for your understanding and patience as Microsoft works on improving Copilot experiences. If any official updates are released, I will strive to share them promptly.
Warm regards.
