Right.  Group 544 is not in a user token of a non-elevated process(*).


(*) More exactly, it is in the token, but with the "Deny only" attribute
    and missing the "Enabled" attribute.  Therefore it will not show up
    as part of the token's group list in Cygwin, because Cygwin skips
    all non-enabled groups.
