Securing a Windows PC is critical for protecting your personal information, online privacy, and overall system health. Windows 10 and 11 offer many built-in security features, but their effectiveness depends on how they’re configured. This comprehensive guide covers actionable steps for both beginners and advanced users to harden your system and maintain privacy.
Getting Started: Essential Security Settings for All Users
1. Keeping Windows Updated
Regularly updating Windows is the foundation of a secure system.
How to check for updates:
– Click Start, then Settings (the gear icon).
– Select Update & Security > Windows Update.
– Click Check for updates and install any available.
Why it matters: Updates patch security vulnerabilities and improve system reliability.
2. Setting a Strong Password or Enabling Windows Hello
A secure sign-in method is your first defense.
How to set this up:
– Go to Settings > Accounts > Sign-in options.
– Choose a strong password, PIN, or enable Windows Hello (fingerprint, face recognition).
Best practice: Use at least 12 characters with a mix of letters, numbers, and symbols.
3. Enabling Windows Defender Antivirus
Windows Defender offers real-time protection against threats.
How to confirm protection:
– Open Settings > Update & Security > Windows Security.
– Click Virus & threat protection. Ensure Real-time protection is ON.
Tip: Avoid installing multiple third-party antivirus programs, as conflicts can reduce security.
4. Configuring the Firewall
The built-in Windows Firewall helps control data entering or leaving your PC.
How to verify firewall status:
– Go to Settings > Update & Security > Windows Security.
– Click Firewall & network protection. Ensure it’s ON for all profiles (Domain, Private, Public).
Practical example: If you connect to public Wi-Fi, keep “Public network” firewall enabled to block unwanted access.
Intermediate Techniques: Increasing Privacy and Reducing Data Exposure
1. Managing Privacy Settings
Windows collects some user data by default. You can limit this:
– Go to Settings > Privacy.
– Review each section (General, Speech, Inking & Typing, Diagnostics & Feedback, Activity History).
– Turn off options you don’t need, especially under Diagnostic data (set it to “Required” data only).
Example: Disable “Let apps use advertising ID” under the General tab to reduce tracking.
2. Controlling App Permissions
Control which apps can access your camera, microphone, location, and more.
– In Settings > Privacy, click on each permission (e.g., Microphone, Camera).
– Turn off access for apps you don’t trust or use.
3. Using BitLocker Drive Encryption (Pro and Enterprise Editions only)
BitLocker encrypts your entire drive, protecting data if your device is lost or stolen.
How to enable BitLocker:
– Search for BitLocker in the Start Menu.
– Select Turn on BitLocker and follow the on-screen instructions.
– Save your recovery key in a safe place.
Advanced Techniques: For Experienced Users
1. Configuring User Account Control (UAC)
UAC helps prevent malware from making unauthorized changes.
How to adjust UAC:
– Search for UAC in the Start Menu.
– Move the slider to “Always notify” for maximum security.
2. Setting Up Local vs. Microsoft Accounts
A local account can reduce the data Microsoft collects, while a Microsoft account offers cloud integration.
– For maximum privacy, create a local account: Settings > Accounts > Your info > Sign in with a local account instead.
3. Using Group Policy Editor (Windows Pro and above)
Advanced users can fine-tune security settings using the Group Policy Editor.
Common tweaks:
– Restrict access to Control Panel and Settings.
– Force complex password policies.
– Disable telemetry and data collection.
How to access:
– Press Win + R, type gpedit.msc, and press Enter.
Example: To require complex passwords:
– Navigate to Computer Configuration > Windows Settings > Security Settings > Account Policies > Password Policy.
– Set “Password must meet complexity requirements” to Enabled.
4. Managing Services and Startup Programs
Disabling unnecessary services reduces attack surfaces.
How to manage:
– Open Task Manager (Ctrl + Shift + Esc), go to Startup tab, and disable unneeded apps.
– For services, search for “services.msc” in the Start Menu and set unwanted services to Manual or Disabled.
Privacy-Focused Maintenance with Glary Utilities
For ongoing maintenance and privacy protection, Glary Utilities offers a suite of tools:
– Tracks Eraser: Clears browsing and usage history, reducing the risk of data leaks.
– Startup Manager: Controls which programs run at startup, improving security and boot times.
– Disk Cleaner: Removes temporary files and potential privacy risks.

– Disable location access unless needed.
– Use Glary Utilities’ Tracks Eraser before traveling to clear sensitive information.
– Ensure your firewall is active, especially on public Wi-Fi.
Conclusion

Advanced users can leverage features like BitLocker, Group Policy, and service management for even stronger protection. Regular maintenance, especially using tools like Glary Utilities, ensures your PC remains secure and private in the long run. With these steps, you’ll have a robust defense against common threats in Windows 10 and 11.
