Windows 11 (or 10) doesn't include an option to schedule an automatic shutdown of your computer, but it's possible to use different tools to complete this task without having to resort to third-party applications.
If you must turn off the computer after a specific time, you have at least seven ways. You can use commands with PowerShell, Command Prompt, and the Run dialog. It's also possible to trigger a shutdown using a shortcut or a batch file.
