 Important:
 - `gpudemod_kernels.dll` must be present next to `sdrd.exe` or in `internal/demod/gpudemod/build/`
-- `build-sdrplay.ps1` copies the DLL to the repo root after a successful app build when available
-- this avoids directly linking MSVC CUDA kernel objects into the MinGW-linked Go binary
+- `build-sdrplay.ps1` prepares the runtime DLL placement and PATH setup for SDRplay + CUDA DLLs
+- older experimental Windows build scripts were removed to avoid confusion
