I need to see the ACLs of the parent dir of test, the ACL of test and
the ACL of test/test via the icacls command, before calling chmod.

It is right if you're using one of those annoying Microsoft accounts
instead of a real local account.  If so, the primary group SID in your
user token is identical to your user SID.  This scenario can't be
easily translated to a POSIX scenario.  The group permissions are set
to 0 in this case to allow security sensitive applications checking file
permissions to function without complaining of too open permissions.
