Do you know which Windows systems still require this workaround? From memory, it was XP.

I know these are copy/paste tests, but since this one passes, can you please check the value?

This was all code to handle a failure in XP. Can you check it's still needed?

         *(DWORD *)*data_bytes = val;
         break;
     }

```
   case REG_QWORD:
```
```
   {
```
```
       LPWSTR rest;
```
```
       UINT64 val;
```

I'd really prefer `WCHAR *` for new code. You can also just use `QWORD` for `UINT64`, although the latter is probably more readable at a glance.
