Windows, in previous versions, included a "Guest" account that allowed you to create a locked-down environment to safely and temporarily share a computer with other people to run apps and access the internet, but this special account is no longer available on Windows 11 (or Windows 10).
However, it's still possible to create a limited account on Windows 11 with the same characteristics of a "Guest" account using the Settings app, Computer Management, Command Prompt, and even PowerShell commands.
