Win11 Explorer: Speed Boost, Dark Fix, Archive Support

🔑 Enhanced Key Takeaways

• •The performance optimizations are primarily driven by a transition to a more efficient XAML-based rendering pipeline, reducing the overhead of the legacy Win32 interop layers.
• •Native archive support now extends beyond ZIP to include RAR and 7z formats via the libarchive integration, significantly reducing the need for third-party utilities like WinRAR.
• •The 'white flash' fix addresses a long-standing race condition in the DWM (Desktop Window Manager) where the window background rendered before the theme-aware UI thread initialized.

🛠️ Technical Deep Dive

• •Implementation of libarchive allows for native read/write operations on compressed formats without spawning external shell processes.
• •Refactoring of the File Explorer process (explorer.exe) to utilize a more robust asynchronous I/O model, reducing UI thread blocking during directory enumeration.
• •DWM integration update ensures that the window frame and client area are initialized in a single atomic render pass, eliminating the frame-buffer flicker during theme switching.
