-Connect from another device using the returned `device_id` and `password`. First-time setup copies the current client's server and codec preferences and creates separate credentials. This ID differs from the GUI client's ID and persists across reboots, logoffs and re-enabling. Subsequent enable commands retain the machine configuration. Self-hosted server root certificates must be trusted in the Local Computer certificate store.
+Connect using the existing `device_id` and `password`. Password changes, device identity keys, and trusted-device records are shared between hosting modes. Re-enabling reuses this identity instead of creating a new ID. Self-hosted server root certificates must be trusted in the Local Computer certificate store.
 
-Once enabled, `CrossDeskService` starts automatically at system boot. Windows automatic login and saved Windows login passwords are unnecessary. The service launches a windowless SYSTEM host in the active console session and reuses secure-desktop capture, keyboard/mouse input and `Ctrl+Alt+Del`. Signing in, locking Windows or closing the ordinary client does not stop it. Logoff, user switching or a host crash causes the service to restart the host; the connection may drop, and you can reconnect using the same ID. Network connections retry if networking is unavailable during boot.
+Once enabled, `CrossDeskService` starts at system boot without Windows automatic login or saved Windows login passwords. A windowless SYSTEM host owns network connections, capture, keyboard/mouse input, and `Ctrl+Alt+Del`. The GUI attaches after the user desktop unlocks without another signaling login or replacing the remote connection. Closing or restarting the GUI preserves viewing and input. Logoff, switching Windows sessions, service restarts, or network failures can still require reconnection; networking retries if unavailable during boot.
 
-Unattended mode supports screen viewing, keyboard/mouse input, monitor switching and secure desktops. Audio, file transfer, clipboard and privacy screens are unavailable. Portable and Debug builds cannot enable it. Configuration and credentials reside in `%ProgramData%\CrossDeskUnattended`, accessible only to SYSTEM and administrators; logs are in its `logs` subdirectory.
+Before sign-in, screen viewing, keyboard/mouse input, monitor switching, and secure-desktop control are available. Once the GUI attaches, audio, file transfers, clipboard, and privacy screens run in the signed-in user process over the existing background connection; file operations do not run as SYSTEM. Those user features pause when the GUI exits and resume when reopened. Portable and Debug builds cannot enable this mode. Shared identity resides in `%ProgramData%\CrossDeskUnattended`, accessible only to SYSTEM and administrators; logs are in its `logs` subdirectory.
+
+Without a physical monitor, the unattended host attempts to prepare a virtual display before accepting connections, preferring a previously recorded resolution and using 1920 × 1080 when no valid record exists. These temporary modes do not overwrite persistent Windows display configuration. Once a physical display is stable, the temporary virtual display is released while preserving the remote stream index.

-On **2026-10-25**, 16 images were rendered from the actual Slint components at `ae6f81e8`: ten refreshed images (main window, General settings, DeskHub settings, self-hosting, and About) and six additions (Direct IP mode, its password dialog, and Network settings), in Chinese and English. Later that day, the four General and Network settings images were refreshed from the working tree after removing Enable TURN Service and separating Self-Hosted Config into a label, Edit button, and switch. The capture-only program reused the existing helper functions in an external temporary directory, using Slint 1.17.1 on macOS arm64 at 2× scale. Capture did not modify product components or repository tests, and no listeners or remote sessions were opened. IDs, IPs, passwords, device records, connection states, and update results are illustrative; `LAN` labels indicate record type, not an online check. The checked Remember password box is a demonstration choice. The four DeskHub enlarged-view and session-video images remain from 2026-10-19, public-page fixtures from 2026-09-07, and the Web image from 2026-09-25. Native mobile screenshots are not included.
+On **2026-11-11**, **22 desktop images** were refreshed and **4 file-transfer and feedback images** were added using the actual Slint components at `6414f231`, Slint 1.17.1 on macOS arm64, and 2× software rendering. The external capture program supplies demonstration data only: it starts no application runtime, listeners, remote sessions, file browsing, transfers, log export, or online update checks. No repository tests were added or changed. IDs, passwords, paths, file metadata, device states, resolution choices, and the `development` version are illustrative. Public-page fixtures remain from 2026-09-07, the Web image from 2026-09-25, and CLI output captures from 2026-10-31; native mobile screenshots are not included. Temporary source, binaries, and PPM files stay outside the repository.
