Microsoft Office 97 (Office 8.0) included hundreds of new features and improvements, such as introducing command bars, a paradigm in which menus and toolbars were made more similar in capability and visual design. Office 97 also featured Natural Language Systems and grammar checking. Office 97 was the first version of Office to include the Office Assistant. In Brazil, it was also the first version to introduce the Registration Wizard, a precursor to Microsoft Product Activation. With this release, the accompanying apps, Project 98 and Publisher 98 also transitioned to fully 32-bit versions.
