What is it?
Microsoft Access Wizard Controls provides several quick-create form tools on the Create tab, each of which lets you create a form with a single click. However, if you want to be more selective about what fields appear on the form, you can use the Form Wizard instead.
Description of accwiz.dll from Microsoft
“A Microsoft® Access wizard is an add-in that can be integrated into the Access user interface. You can create a table, query, form, or report wizard, which appears in the list of options in the New Table, New Query, New Form, or New Report dialog box. For example, you can design a wizard to help users build complex queries, such as update queries. In addition, you can create control wizards, which are launched when users create new controls on a form or report. Users can disable control wizards by toggling the state of the Control Wizards tool in the toolbox.”
