🔐 10 Essential Cybersecurity Tips for Windows 11
Protect your digital life now.
These simple yet technical tips will strengthen the security of your Windows 11 system against today's threats.
🔐 1. Cybersecurity: Enable Ransomware Protection
Windows 11 includes a key feature: Controlled folder access, designed to stop ransomware from tampering with your sensitive files.
Why it matters:
Block unauthorised access to your personal documents (Pictures, Documents, Desktop, etc.).
How to enable it:
Windows Security > Virus & threat protection > Manage ransomware protection
➡️ Enable Controlled folder access
➡️ Manually add your trusted applications
🧠 Pro tip: Test with an unknown application to check the effectiveness of real-time protection.
🔐 2. Encrypt Your Drive with BitLocker
Protect your data in case of theft or loss.
Why BitLocker:
Without the recovery key, your data is unreadable, even if someone gains physical access to the drive.
Activation:
Control Panel > System and Security > BitLocker Drive Encryption
➡️ Enable BitLocker for each drive
➡️ Back up your recovery key in a secure place
⚠️ Never forget: Without the key, your data is permanently inaccessible.
🔐 3. Use a Standard Local Account
Limit the privileges of your main session to reduce risk.
Why it's vital: A standard account blocks the silent installation of malicious software.
What to do:
Settings > Accounts > Family & other users
➡️ Create a standard local account
➡️ Reserve the administrator account for system tasks
💡 Bonus tip: Disable the default “Administrator” account.
🔐 4. Strengthen Windows Defender with a Third-Party Anti-Malware
Windows Defender is good, but Malwarebytes adds a complementary layer of security.
Why double protection?
Detection of advanced malware and PUPs (potentially unwanted programs).
Installation:
➡️ Download Malwarebytes Free
➡️ Run weekly scans
⚠️ Important: Do not run two real-time antivirus programs.
🔐 5. Disable Unnecessary Network Services
Fewer services = a smaller attack surface.
To disable:
- Settings > System > Remote Desktop
- ➡️ Disabled
- Settings > Network & Internet > Sharing options
- ➡️ Disabled
- Set the network profile to Public
🔒 Security bonus: Use a reliable VPN on public networks.
🔐 6. Update Windows and Your Drivers
Updates fix critical vulnerabilities.
To check regularly:
Settings > Windows Update
➡️ Enable automatic updates
For drivers:
➡️ Use a tool such as Driver Booster or visit the manufacturer's website
⚠️ Warning: Avoid drivers from unofficial sites.
🔐 7. Control the Applications Allowed Through the Firewall
Windows Firewall protects you, but it deserves fine-tuning.
What to do:
Windows Security > Firewall & network protection > Allow an app through firewall
➡️ Remove obsolete or dubious applications
🚫 Advanced tip: Use the advanced firewall or PowerShell to block ports or restrict sensitive outbound connections.
🔐 8. Customise Your Privacy Settings
Reduce Microsoft's default data collection.
To disable:
Settings > Privacy & security
➡️ Camera, microphone, location
➡️ Background apps
➡️ Sending of extended diagnostics
🔧 Recommended tool: O&O ShutUp10++ for granular control.
🔐 9. Enable Two-Factor Authentication (2FA)
Protect your Microsoft account against unauthorised access.
Activation:
➡️ Go to account.microsoft.com
➡️ Security > Advanced security options tab
➡️ Enable two-step verification
🔐 Preferred: Use an app such as Microsoft Authenticator rather than SMS.
🔐 10. Use a Password Manager
Avoid weak passwords such as “123456” or “password”.
Recommended tools:
- Bitwarden – open source and free
- KeePassXC – for local use
- 1Password – for professionals
Why?
➡️ Generates, stores and syncs strong passwords
➡️ Enhanced protection with 2FA
