Wouldn't it be better to use some other GUID here:

+    hr = pCoGetTreatAsClass(&GUID_NULL,&out);
+    ok (hr == S_FALSE, "expected S_FALSE got %x\n",hr);
+    ok (IsEqualGUID(&out,&GUID_NULL), "expected to get same clsid back\n");

That way we would know if Windows indeed leaves the clsid alone or 
returns the NULL GUID?

Something like:

static GUID deadbeef = 
{0xdeadbeef,0xdead,0xbeef,{0xde,0xad,0xbe,0xef,0xde,0xad,0xbe,0xef}};
