Claude Desktop's Unified Claude interface becomes default for all organizations

Anthropic made Unified Claude, the merged Chat and Cowork interface in Claude Desktop, the default experience for any organization that has not explicitly set the desktopHome configuration key, starting with launches after 12:00 PM PT (20:00 UTC) on November 10, 2026, according to the Claude Desktop configuration changelog.

What changed

• Any organization that leaves the desktopHome config key unset now has it automatically set to standard, turning on Unified Claude organization-wide.
• Unified Claude merges the previously separate Chat and Cowork interfaces into one UI that exposes Cowork's agentic capabilities.
• The automatic switch overrides prior org settings such as coworkTabEnabled: false and chatSessionRetentionDays, which used to be able to block or delay the change.
• Admins who want to keep Chat and Cowork separate, or disable one of them, must explicitly set desktopHome, for example to off, which disables both Chat and Cowork while leaving Claude Code unaffected.
• The coworkTabEnabled, chatTabEnabled and chatAdvancedFileAnalysisEnabled keys are deprecated in favor of desktopHome, and admins still using them will see deprecation warnings starting November 17, 2026.

Why it matters for builders

IT and security admins running Claude Desktop fleets had to act before November 10, 2026, or their users would be switched into the agentic, Cowork-enabled interface by default, even if they intended to keep it off. Because chatSessionRetentionDays and coworkSessionRetentionDays are configured separately, with Cowork task conversations deleted only by the latter, teams that rely on a single retention setting need to review both keys to keep chat and agentic session data handled the way they expect.

Rollout and next steps

The change is documented across Claude Desktop and Cowork configuration changelog entries dated October 29, 2026 (v4.4212.0) and November 3, 2026 (v4.16336.0). Ahead of the switch, Claude Code changelog entry 2.1.319 from November 6, 2026 added startup warnings in the Claude apps gateway for org policies that lacked a desktopHome setting. Admins can follow further updates in the Claude Cowork changelog.
