AWS appstream2: Clarify application settings persistence is Windows-only

Service: appstream2 · 2026-11-05 · Documentation low

File: appstream2/latest/developerguide/agent-access-mcp-session-behavior.md

Summary

Updates the application settings persistence paragraph to state the feature is available on Windows and not supported on Linux; the rest of the S3 persistence description is unchanged.

Security assessment

The change only adds a platform-availability qualifier (Windows only, not Linux) to an existing feature description; the pre-existing S3 access statement is retained and no new security control, vulnerability, or advisory is introduced.

Evidence

+You can optionally enable application settings persistence. This setting is available on Windows and is not supported on Linux. When enabled, your agent's application customizations and Windows settings are saved after each streaming session and applied during the next session. These settings are saved to an Amazon S3 bucket in your AWS account. The Amazon WorkSpaces Applications fleet associated with the stack must allow access to Amazon S3 through the internet or an Amazon S3 VPC endpoint. For more information, see [Enable application settings persistence for your users](https://docs.aws.amazon.com/appstream2/latest/developerguide/app-settings-persistence.html).
