Desktop app lost Chat after forced update; only Search mode.

Because Chat still works on the web, the desktop failure does not by itself establish that your Family subscription lost entitlement. Windows administrator rights also do not determine which Copilot account experience you receive; Microsoft documents separate personal and work or school experiences.

First compare the signed-in account and its Personal or Work label in the desktop app with the working browser session. Sign out of the desktop app and sign back in with that same personal Microsoft account. Also confirm the installed app and version against the current Microsoft Store listing, since the app naming has changed.

Check your conversations and Library in the working web experience before assuming the history and saved content were deleted. If desktop still shows only Search, add the app version, update time, and navigation screenshot to your support case. There is no confirmed licensing-server diagnosis in the information provided.
