10 Windows 11 Security Tweaks That Actually Matter

Apply these and you’re already ahead of most users.

This checklist is meant for normal users, small businesses, and anyone who wants to harden Windows 11 quickly without turning it into a locked-down mess.

1. Turn on device encryption

Ensure BitLocker or “Device Encryption” is enabled so a stolen laptop doesn’t expose your files.

2. Use a strong sign-in method

Use Windows Hello (PIN, fingerprint, face) tied to your account, not a simple local password.

3. Keep Windows Update enabled

Do not disable updates. Schedule restarts if needed, but let security patches install.

4. Enable SmartScreen

Keep Microsoft Defender SmartScreen enabled for apps and browser to block known malicious files and sites.

5. Run Microsoft Defender

For most users, built-in Defender is enough. Make sure real-time protection and cloud protection are turned on.

6. Limit admin rights

Use a standard account for daily work when possible. Only elevate when needed.

7. Check startup apps

Disable junk in Task Manager → Startup apps. Less clutter, fewer potential risks.

8. Review app permissions

In Settings → Privacy & security, review which apps can use microphone, camera, location, etc.

9. Use a password manager

Don’t reuse passwords. Use a reputable password manager and enable 2FA on important accounts.

10. Backup something

Use File History, OneDrive, or another backup method. Security without backup is an illusion.
