When permissions entries only show a View button, not Edit

Earlier today, I answered this Super User question, the poster of which was confused as to why some entries in the advanced security settings for Windows files changed the Edit button's label to View and couldn't be modified.

That happens when the entries are inherited from the parent object. Access control entries are evidently supposed to be modified on the object that originated them.

If you need to change or remove those entries, you can click the Disable inheritance button and choose to convert the inherited entries to explicit entries on the object.

The top option converts inherited entries

Once that's done, the View button will become Edit, and you'll be able to change the entry's settings.
