There's also something strange going on when the DLL is registered, which needs to be sorted out.
The registered module path includes a `drivers` component (ie: `"DllPath"="C:\windows\system32\drivers\windows.system.profile.systemmanufacturers.dll"`), which I think is incorrect.
I think it also breaks the wow64 tests, running the 32bit tests in a 64bit prefix, somehow. I didn't investigate, but a wild guess would be that it's maybe because of the very long module name.
