✨ Features

• 🔍 Detailed OS Info: Displays OS Name, Edition, OS Build (including UBR), and Architecture.
• 🔑 Advanced Key Decoding: Uses a character map (BCDFGHJKMPQRTVWXY2346789) and bit-wise operations to decode the binary DigitalProductId from the registry.
• 📋 Clipboard Support: Dedicated "Copy" buttons for every field, including a formatted version of the Installation ID.
• 🧠 Multi-Method Retrieval: Combines Registry decoding with CIM/WMI fallbacks to ensure information is captured even on different license types.
• 🖥️ Modern UI: Responsive dark-themed WPF GUI with high-contrast text and "toast" notifications when data is copied.
• ⚡ Performance Optimized: Features CIM session caching, batched registry reads, and pre-compiled regex patterns.
• 🛡️ Self-Elevation: Automatically detects if it is running without privileges and prompts to restart as Administrator.
