Wallpaper Identity v4.0.1

Wallpaper Identity v4.0.1

Version 4.0.1 is a lock-screen reliability release. It adds the documented Windows Pro policy path, replaces false-positive health with exact Windows readback, hardens service shutdown and unattended deployment, and clearly distinguishes a current boot-generated file from the bitmap Windows may already have cached for LogonUI.

Windows Pro compatibility

• Enables Microsoft's documented SetEduPolicies compatibility switch on Windows 10/11 Pro by default
• Does not enable Shared PC mode, account cleanup, power policies, kiosk mode, or storage restrictions
• Clearly documents the three effects of SetEduPolicies: Windows tips, advertising ID, and Microsoft consumer experiences are disabled
• Adds enable_pro_compatibility to config.yml for explicit power-user opt-out
• Backs up the previous SetEduPolicies state and positively verifies its restoration during uninstall

No more false-positive health

• Reads back every Group Policy value after writing it
• Waits for MDM_Personalization to report status 1 for the exact generated image URL
• Stages CSP delivery images in a space-free path because the Pro provider did not complete file URLs containing spaces
• Requires both verified SetEduPolicies and verified Personalization CSP state on Pro
• Reports a failed refresh and unhealthy CLI status when Windows has not accepted an effective policy
• Normalizes stale rollback records owned by version 3 or an earlier W:ID installation instead of restoring a deleted image path

Service and deployment robustness

• Reports the Windows service as running before starting potentially slow CSP work, avoiding Service Control Manager startup timeouts
• Keeps the initial render serialized ahead of boot-settled, session, timer, and RMM refreshes
• Gives an in-flight worker a bounded 30-second drain on stop/shutdown so CSP latency cannot indefinitely block Windows shutdown
• Extends bounded setup and uninstall waits for slow policy providers
• Verifies LocalSystem device-policy rollback before uninstall removes recovery files
• Correctly restores an absent or empty prior CSP lock-screen value without deleting the Personalization singleton or an unrelated desktop-image setting

Windows-managed display cache

• The automatic service does generate during boot and captures an IP address that changed while the machine was powered off
• Every layout permanently includes a timezone-qualified Generated at value
• Windows 11 Pro can still display its previous verified bitmap on the first pre-login frame even after the new file and CSP status are current
• W:ID does not add an ineffective boot delay, replace a credential provider, or terminate security-sensitive LogonUI to bypass that Windows behavior

The release remains self-contained and offline. Use WallpaperIdentitySetup.exe for the graphical installer or WallpaperIdentityCLI.exe for blocking, headless RMM deployment.

Screenshots

The pre-login image is a real service-rendered example. As documented above, Windows may show its previously cached verified bitmap on the first LogonUI frame even when W:ID's boot-generated file and policy are current.
