Developer notes (why this happens to apps)

• The API-set DLLs are forwarding/adapter layers. Apps built against newer Windows SDKs or the Universal CRT may expect these API-set entry points to exist. If runtime components are missing or mismatched, the loader will report the missing DLL even though the functionality lives inside other system libraries.
• Static linking of older runtimes, or bundling incompatible DLLs with an app, can also produce similar loader errors.
