Please use an array for protocol_clsid and `StringFromGUID2` here to avoid allocation. Other than that, the patch looks good to me.

can I do

```c
static WCHAR protocol_clsid[ARRAY_SIZE(null_guid)];
```

or do I have to

```c
static WCHAR protocol_clsid[39];
```

?

Or maybe there is a constant defined for the length of a GUID string?

Ah there is `CHARS_IN_GUID`
