StreamShield interacts with low-level Windows APIs (SetWindowDisplayAffinity) by injecting dynamic libraries into target processes. Maintaining process boundaries and user trust is central to its architecture.

• UAC Elevation Model: StreamShield requests standard User Account Control (UAC) elevation on launch (requireAdministrator). This ensures the process operates at High Mandatory Integrity Level to safely communicate with both elevated and standard desktop windows without security token mismatches.
• Non-Destructive Hooking: The injected DLL (shield_dll.dll) exclusively targets window compositing display affinity flags. It executes zero memory patching, zero code hooking (e.g. no Detours/MinHook byte splicing), and zero arbitrary code execution.
• Process Boundary Isolation: All process enumeration queries verify target window visibility prior to thread creation to eliminate visual artifacting or target instability.
