Essential Windows Security Settings

Essential Windows Security Settings

After installing Windows, securing your system is just as important as optimizing it. 

With cyber threats increasing daily, activating essential security features helps protect your data and ensures your PC remains safe from malware, ransomware, and hackers.

1. Enable Windows Security (Defender)

Windows comes with built-in antivirus and security software called Windows Security (formerly Windows Defender).

How to enable :

• Go to Settings > Privacy & security > Windows Security

• Click Open Windows Security

• Make sure the following are enabled:

  • Virus & threat protection

  • Account protection

  • Firewall & network protection

  • App & browser control

  • Device security

You do not need a third-party antivirus unless you need advanced protection.

2. Enable and Configure the Firewall

A firewall blocks unauthorized access to your PC.

Check status :

• Go to Windows Security > Firewall & network protection

• Ensure it says "Firewall is on" for all networks (Domain, Private, Public)

Do not disable this unless absolutely necessary for troubleshooting.

3. Keep Windows Updated

Security patches are included in Windows Updates.

To stay up to date :

• Go to Settings > Windows Update

• Enable Automatic Updates

• Regularly check for updates manually

4. Set Up a Strong Password or PIN

Avoid using simple or default passwords.

Recommended :

• Use a mix of uppercase, lowercase, numbers, and symbols

• Enable PIN login or Windows Hello (facial or fingerprint) if supported

• Avoid using the same password across sites

5. Enable BitLocker Drive Encryption (Pro Editions)

BitLocker encrypts your entire drive, protecting it if your PC is lost or stolen.

How to enable :

• Search for BitLocker

• Select your system drive (usually C:) and click Turn on BitLocker

BitLocker is only available on Windows Pro and Enterprise editions.

Unless you need it for remote access, it’s safer to disable RDP.

• Toggle off the switch

8. Limit App Permissions

Do not give unnecessary apps access to your data.

How :

• Go to Settings > Privacy & security > App permissions

9. Create a System Restore Point

If a malware attack happens, you can roll back safely.

How to create :

10. Back Up Important Files Regularly

Use File History, OneDrive, or external drives to back up critical data. Backups are essential in case of malware, drive failure, or accidental deletion.

Properly securing your Windows system should be a top priority after installation. 

By enabling these essential security settings, you can protect your personal data, block malicious attacks, and ensure a safer computing experience from day one.
