Wallpaper Identity v4.0.0

Wallpaper Identity v4.0.0

Wallpaper Identity is the new end-to-end identity for the pre-login machine-status project. Its shorthand is W:ID.

Rebrand

• New Wallpaper Identity name and W:ID shorthand across the installer, service, executable, overlay, configuration, documentation, repository, CI artifact, and release package
• New professionally generated W:ID folded-wallpaper logo
• Branded Windows executable icon, manifest metadata, Apps & features entry, title bars, installer header, and pre-login image
• New WallpaperIdentitySetup.exe release artifact
• New WallpaperIdentityCLI.exe console-subsystem artifact for reliable RMM waiting, JSON, result files, and exit codes
• Repository move to github.com/amcchord/WallpaperIdentity and semantically versioned Go module github.com/amcchord/WallpaperIdentity/v4

Safe upgrade from version 3

• Detects and stops the previous service automatically
• Migrates config.yml, generated images, status, logs, and policy/MDM rollback files into C:\ProgramData\Wallpaper Identity
• Preserves custom configuration values while rewriting the generated YAML header for W:ID
• Replaces the previous install directory, service, executable, and Apps & features entry
• Retains the original pre-install policy backup so uninstall still restores the correct Windows state
• Recognizes previous-version image ownership during rollback without exposing the old identity in active UI

Existing v3 capabilities retained

• Fastfetch-inspired, resolution-aware Identity, Balanced, and Operations layouts
• Automatic LocalSystem refresh during boot, after boot settles, every five minutes, and on session/power events
• Permanent hostname and timezone-qualified Generated at text
• Supported Group Policy and LocalSystem MDM_Personalization application paths
• Windows 11 top-center and Windows 10 lower-left clock-safe layout
• Offline graphical installer, repair/upgrade, rollback-aware uninstall, and Apps & features registration
• No LogonUI.exe termination, credential provider, network listener, updater, or outbound dependency

Headless and RMM deployment

• True console-subsystem CLI that is headless by default and blocks until each operation completes
• Install, repair/upgrade, status, LocalSystem refresh, preview render, and rollback-aware uninstall commands
• Strict preflight validation for presets, YAML, absolute local JPEG/PNG base images, and conflicting result targets before installation state changes
• Versioned JSON and atomic result-file output with stable error codes, 1618 concurrency handling, and standard success/reboot code 3010
• Named global setup lock shared by graphical and CLI entrypoints
• --remove-data purge semantics that retain recovery data on rollback failure

Compatibility

Fully supported targets are Windows 10/11 Enterprise, Education, IoT Enterprise, and Windows Server. Windows 11 Pro accepts the policy writes but retains its stock image unless an administrator separately configures Microsoft's broader SharedPC/BootToCloud prerequisites. W:ID does not enable those settings automatically.

Validation

• Automated unit, migration, renderer, race, vet, and Windows CI checks
• Windows 11 Enterprise: v3-to-W:ID in-place upgrade, migrated configuration, healthy automatic LocalSystem service, and successful policy application before a Windows servicing reboot
• Windows 10 Enterprise: service/policy and clock-safe pre-login baseline validated; v4 binaries staged, with the final live upgrade deferred by Windows servicing
• Windows 11 Pro: branded installer/config/render validation and expected policy limitation
• Upgrade cleanup and rollback-aware uninstall verification
