> Yes, `PSGetNameFromPropertyKey` returns `TYPE_E_ELEMENTNOTFOUND` for unknown keys, so using the custom property syntax is something the caller needs to do:

```c
 PROPERTYKEY key = { 0 };
 WCHAR* name;
 HRESULT hr;

 key.pid = 0xdeadbeef;
 hr = PSGetNameFromPropertyKey( key, &name );
 printf( "hr: %#lx\n", hr );
```

That being said, we probably should log a FIXME in `PSGetNameFromPropertyKey` before returning TYPE_E_ELEMENTNOTFOUND.
