Microsoft added the WinML API in Windows 10 1809 and later versions. We can use this API to run ONNX models for tasks such as OCR.

Possible advantages and disadvantages:

Advantages:

• No need to bundle ONNXRuntime; instead, use ONNXRuntime bound to WinML to reduce the size of the installation package.
• WinML handles various hardware calls, enabling the use of high-performance GPUs.

Disadvantages:

• Requires writing C++ code, which may not be as flexible as ONNXRuntime.
• Using the system-bound WinML is less reliable than using a self-bundled WinML.
