Windows 11 includes grammar features that enhance writing across applications. Users need to manually configure these tools in specific applications like Notepad, Outlook, and Microsoft 365. To enable grammar tools, users can go to Settings, then Time & language, and select the Typing page to activate autocorrect and spellcheck features. Users can also monitor typing statistics and manage a custom dictionary through the Privacy & security settings. For specific applications, users can enable spelling features in Notepad by accessing settings and toggling spell check, in Microsoft Edge by enabling grammar assistance in the settings menu, in Outlook by adjusting editor settings, and in Microsoft 365 apps by checking proofing options in the app settings.
