It didn't fail at all actually. I tried with different combinations of `MF_MT_SUBTYPE`, `MF_MT_AM_FORMAT_TYPE` and with and without `MT_USER_DATA` and Windows accepted everything. Seems like there's no need for any check when `MT_USER_DATA` is missing. So I have pushed a change to the MR accordingly.

The check has now been removed.
