Description

This PR refactors the deployment process by shifting registry modifications and AppX package removal out of the initial ISO build phase and into the Post-OOBE (Out-of-Box Experience) phase. It also includes comprehensive script refactoring, asynchronous runspace handling for image operations, and major optimizations to the build pipeline.

Key Architectural Changes & Rationale

• Asynchronous Threading & UI Responsiveness: Ported intensive disk and image-handling tasks (like Mount-DiskImage, Dismount-WindowsImage, and Export-WindowsImage) into isolated background runspaces (STA). This prevents the main WPF thread from freezing, ensuring a responsive user interface during heavy operations.
• Efficient Environment Staging: Injecting registry tweaks and removing AppX packages directly inside the offline ISO image is inefficient. Executing these changes post-OOBE is significantly faster, reduces complexity, and simplifies long-term codebase maintenance.
• Streamlined User Experience: A PowerShell script now executes during the final post-OOBE setup phase (the blue "This might take a few minutes" screen). Upon completion, the machine reboots directly into a clean, fully configured desktop environment.
• Dynamic Script Execution: Because FirstLogon.ps1 is fetched dynamically during setup, script updates can now be pushed directly to the repository without requiring an entirely new ISO build from scratch.
• Removed Update-Disabling Logic: Disabling updates prior to OOBE has been removed because Windows natively allows users to skip updates during this stage. (Note: Mandatory update checks still occur, which the previous pre-OOBE method did not prevent anyway).

Optimizations & Cleanup

• Remove /Resetbase: This operation takes a long time and only removes about 20 mb so i decided to remove it
• Log Display Adjustments: Simplified the logger layout behavior; logs no longer append to a massive new-line string, allowing the interface to display a cleaner, singular current status message at a time.
• Code Simplification: Removed redundant metadata handling functions (such as Get-DismImageInfoMap and the previous Hydration WIM fix), as testing indicated they introduced unnecessary overhead without resolving underlying issues.
• Native File Operations: Replaced external robocopy calls with native Copy-Item configurations to better leverage PowerShell integration and improve local file duplication performance.
• Console Noise Reduction: Suppressed verbose output for oscdimg commands to keep the processing logs clean, focused, and legible.
• Boot.wim Driver Injection Fix: Stopped incorrect driver injection paths from leaking into boot.wim during the Windows 11 image creation process.
• Clean & Reset Optimization: Re-architected the "Clean & Reset" workspace routine to explicitly delete targeted files and paths directly instead of passively scanning for them, drastically reducing execution and cleanup turnaround time.
