In creating a new list content type, I changed the Title column to another name and inadvertently changed it in EVERY list of the ENTIRE site collection. I can't change it back via the Change Site Column page because Title is a reserved word in _Hidden group, which is inaccessible to me. Any way to change this back to the default column name without having to restore to a previous version of the site collection?Thanks,Shelly

Hi, I think it is not possible to change this back to the default column name except restoring to a previous version of the site collection. Changing a site column’s display name can be done at the list level; these customizations are not applied to the parent site content type. And renaming an out-of-the-box site column name is not recommended. Hope it helps.Xue-Mei Chang
