How to Secure a Windows 11 PC

Windows 11 includes several security features, but good security still depends on configuration and user habits.

Keep Windows Updated

Install Windows security updates and keep browsers, applications, drivers, and security software current.

Use Strong Authentication

Use strong passwords and enable multifactor authentication wherever it is supported. Windows Hello can provide convenient device authentication on compatible hardware.

Protect the Endpoint

Keep Microsoft Defender or another reputable endpoint security product enabled and configured appropriately.

Back Up Important Data

Security is not only about prevention. Maintain reliable backups so important files can be recovered after hardware failure, accidental deletion, or ransomware.

Use Least Privilege

Use standard user accounts for everyday activities where practical and limit administrative access.
