Windows 10 and 11 continue to dominate the desktop market, but their widespread use also makes them prime targets for cyber threats and privacy intrusions. Enhancing your PC’s security and privacy is not only about using antivirus software or tweaking a few settings—it’s about understanding common pitfalls and adopting proven methods that deliver real protection. This article explores practical strategies to boost your Windows security and privacy, highlighting common mistakes to avoid, with step-by-step advice for beginners and advanced users.
Why Security and Privacy Matter on Windows
Your Windows PC stores sensitive data, work files, personal photos, and more. Cybercriminals exploit vulnerabilities, while companies can potentially collect more data than you intend to share. By strengthening your security and privacy posture, you prevent data breaches, malware infections, and unnecessary data collection.
Beginner Section: Essential Steps and Common Mistakes
1. Not Keeping Windows Updated
Mistake: Many users ignore or postpone Windows Updates, fearing disruptions. However, updates often contain crucial security patches.
Action:
Go to Settings > Update & Security > Windows Update.
Click “Check for updates” and install all available updates.
Set updates to install automatically for future protection.
2. Skipping Antivirus and Firewall Basics
Mistake: Disabling Windows Defender or firewall for convenience, or running two antiviruses at once (causing conflicts).
Action:
Ensure Windows Security (or your chosen antivirus) is active. Check under Settings > Update & Security > Windows Security.
Keep the built-in Windows Firewall enabled. Do not disable it unless troubleshooting with expert guidance.
3. Overlooking Privacy Settings
Mistake: Installing Windows with default settings, which enable broad data sharing.
Action:
Open Settings > Privacy.
Review the categories (e.g., Location, Camera, Microphone, Diagnostics).
Toggle off unnecessary permissions. For example, disable microphone access for apps that don’t require it.
4. Weak or Reused Passwords
Mistake: Using short, simple passwords or the same password across accounts.
Action:
Use strong, unique passwords for your Windows login and online accounts.
Consider activating Windows Hello (face, fingerprint, PIN) via Settings > Accounts > Sign-in options.
5. Neglecting Account Types
Mistake: Using an administrator account for daily tasks.
Action:
Create a separate standard user account for everyday use. Only log in as administrator for installations or system changes.

1. Not Using BitLocker Drive Encryption
Mistake: Leaving your PC’s hard drive unencrypted means data can be retrieved if your device is stolen.
Action:
If you have Windows Pro or Enterprise:
Go to Control Panel > System and Security > BitLocker Drive Encryption.
Turn on BitLocker for your drives and store the recovery key safely.
2. Failing to Harden Network and Sharing Settings
Mistake: Using public networks without adjusting sharing options exposes your files.
Action:
Open Settings > Network & Internet > Wi-Fi (or Ethernet).
Click on the network, then set it as “Public.”
Turn off network discovery and file/printer sharing.
3. Not Auditing Installed Programs and Startup Items
Mistake: Allowing unnecessary apps and background programs increases your attack surface.
Action:
Use Glary Utilities to manage startup items and uninstall unwanted software:
Open Glary Utilities, go to “Startup Manager” and disable unnecessary entries.
Use the “Uninstall Manager” to remove outdated or suspicious programs.
This reduces vulnerabilities and improves system performance.
4. Ignoring Advanced Privacy Controls
Mistake: Accepting default diagnostic and telemetry settings.
Action:
Go to Settings > Privacy > Diagnostics & feedback.
Set Diagnostic data to “Required only.”
Review and minimize feedback frequency and tailored experiences.
5. Not Regularly Cleaning Browser Data and System Traces
Mistake: Leaving browser history, cookies, and system activity logs accessible.
Action:
Use Glary Utilities’ “Tracks Eraser” to clear browser data and Windows traces on a regular schedule.
This protects your privacy from both online trackers and local snoops.
Real-World Example: Preventing Data Exposure After PC Theft
A user with an unencrypted laptop was the victim of theft. Because BitLocker was not enabled, sensitive files were easily extracted from the hard drive. By enabling BitLocker and using a strong password—plus managing startup items with Glary Utilities—the risk of data loss and exposure drops dramatically.
Summary: Avoiding Mistakes, Staying Secure
Security and privacy on Windows 10 and 11 aren’t about a single switch—they require ongoing, informed management. Avoiding common mistakes—like skipping updates, ignoring privacy controls, or coasting with default settings—makes a big difference. Tools like Glary Utilities can streamline system maintenance, helping you manage startup programs, erase digital traces, and keep your PC clean and secure.
For beginners, focus on updates, antivirus, and privacy basics. Advanced users should leverage drive encryption, hardened network settings, and thorough system audits. Whether you’re just getting started or looking to tighten your defenses, these methods will help keep your Windows PC private and secure.
