Could you build this?
Partial While an Electron or Tauri UI is straightforward, actively monitoring, intercepting, and locking Windows registry default app associations requires low-level Windows API handling and admin-level registry hooks.
What it would actually take: The app requires C++ or C# with P/Invoke to hook into the Windows Registry and Shell APIs (such as IApplicationAssociationRegistration, UserChoice hashes introduced in Windows 8+, and Shell hooks). It must run as a background Windows Service with SYSTEM/Administrator privileges to detect RegNotifyChangeKeyValue events and combat Windows' internal UserChoice protection algorithms designed specifically to prevent programmatic hijacking.
