Here are some strong security settings you can enable on Windows 11 to enhance its security and make it more difficult for hackers to access:

1. Enable Windows Hello: Windows Hello is a biometric authentication feature that uses facial recognition or fingerprint authentication to allow users to sign in to their accounts. It is more secure than a traditional password and helps prevent unauthorized access to your device.

2. Turn on BitLocker: BitLocker is a built-in encryption tool that encrypts your entire hard drive, protecting your data even if someone steals your device. It makes it almost impossible for hackers to access your data without the encryption key.

3. Enable Windows Defender Firewall: Windows Defender Firewall is a built-in firewall that monitors incoming and outgoing traffic and blocks any unauthorized access attempts. It can prevent malware and hackers from gaining access to your system.

4. Keep Windows 11 updated: Microsoft regularly releases security updates for Windows 11 that address known vulnerabilities. By keeping your system up to date, you can ensure that you have the latest security patches installed.

5. Use a strong password: If you are using a traditional password to sign in to your account, make sure it is strong and difficult to guess. A strong password should be at least 12 characters long and include a mix of uppercase and lowercase letters, numbers, and symbols.

6. Disable unnecessary services and features: Disable any services or features that you do not need or use. This can reduce the attack surface of your system and make it more difficult for hackers to gain access.

7. Use a standard user account: Use a standard user account for day-to-day activities and only use an administrator account when necessary. This can limit the damage that malware or hackers can do if they gain access to your system.

By following these security settings and best practices, you can significantly improve the security of your Windows 11 system and reduce the risk of unauthorized access or data breaches.

Be careful with these settings though, but here are some services you might want to disable as well, if you do not use or need them:

1. Print Spooler: This service manages print jobs and can be safely disabled if you do not use a printer.

2. Remote Registry: This service allows remote users to modify the Windows Registry. Disabling it can prevent unauthorized access to your registry.

3. Bluetooth Support Service: If you do not use Bluetooth devices with your computer, you can disable this service.

4. Windows Connect Now: This service is used to configure Wi-Fi and can be disabled if you do not use Wi-Fi or prefer to configure it manually.

5. Remote Assistance: This feature allows other users to remotely control your computer. If you do not use it, you can disable it to prevent unauthorized access.

6. Windows Error Reporting Service: This service sends error reports to Microsoft. While it can be useful for troubleshooting, it can also potentially leak sensitive information. You can consider disabling it if you prefer not to send error reports.

Please note that disabling any services or features can potentially cause issues or network access problems, so it’s important to research each service and feature before disabling it to make sure it is safe to do so.

Additionally, if you’re not sure whether you should disable a particular service or feature, it’s best to leave it enabled to avoid potential issues.
