Windows is a powerful and flexible operating system, but its default settings aren’t always optimized for maximum security and privacy. Whether you’re an advanced user or someone looking to take your privacy and security to the next level, there are practical steps you can take to lock down your system, protect your data, and reduce your exposure to cyber threats. This guide provides expert recommendations and actionable advice tailored for advanced Windows users but presented in a way that all levels can follow.
Why is Enhancing Windows Security and Privacy Important?
With rising cyberattacks, data breaches, and increasing concerns about digital privacy, Windows users need more than basic antivirus protection. Default Windows configurations often prioritize usability over security, potentially exposing you to unnecessary risks. Proactively strengthening your system not only protects your files and personal information but can also improve stability and performance.
What Are the Essential Steps to Secure Your Windows Installation?
1. Turn On and Configure Windows Defender Security Features
Windows Defender offers real-time protection against malware and ransomware, but for advanced users, delve into its advanced settings:
Open Windows Security via Start Menu, then go to Virus & Threat Protection.
Turn on Controlled Folder Access to protect important files from ransomware.
Enable Tamper Protection to prevent unauthorized changes to security settings.
Navigate to App & Browser Control and set reputation-based protection to block potentially unwanted apps.
2. Harden User Accounts & Passwords
Use a local account (when possible) instead of a Microsoft account for increased privacy.
Ensure all accounts have strong, unique passwords.
Enable Windows Hello or two-factor authentication (2FA).
Disable unused accounts and change the default administrator account name to make brute-force attacks harder.
3. Keep Windows and All Software Updated
Hackers often exploit outdated software. Regularly check Windows Update and third-party apps for patches.
Enable automatic updates for Windows and Microsoft Store apps.
Use Glary Utilities’ Software Update tool to scan for outdated programs and streamline updates for third-party software.
4. Uninstall Unnecessary Apps and Features
Remove programs and Windows features you don’t use. Fewer apps mean fewer security vulnerabilities.
Go to Settings > Apps to review installed programs.
Glary Utilities’ Uninstall Manager helps remove stubborn or hidden applications more thoroughly.
How to Manage Advanced Privacy Settings in Windows?
1. Restrict Telemetry and Data Collection
Windows collects diagnostic and usage data. To reduce telemetry:
Go to Settings > Privacy > Diagnostics & feedback and set data collection to Basic or Required.
Disable “Tailored experiences” and automatic feedback requests.
Use local accounts where possible and limit Cortana’s access to personal info.
2. Review App Permissions
Go to Settings > Privacy, and audit app permissions for camera, microphone, contacts, calendar, and more.
Turn off access for apps that don’t need it.
Regularly review permissions after Windows feature updates.
3. Harden Network and Firewall Settings
Ensure that Windows Defender Firewall is enabled for all profiles (public, private, domain).
Set your home Wi-Fi network to “Private” and disable network discovery if you don’t share files.
For advanced users, use Windows Firewall with Advanced Security to create custom rules to restrict inbound and outbound connections.
4. Encrypt Sensitive Data
Turn on BitLocker Drive Encryption for your system drive and any portable drives (Windows Pro and above).
For sensitive folders, use Windows’ built-in encryption (EFS) or a third-party tool for file-level encryption.
What Additional Tools and Practices Enhance Windows Security and Privacy?
1. Use a Comprehensive Maintenance Suite
Glary Utilities isn’t just for cleaning junk files—it features privacy and security tools:
Tracks Eraser securely wipes history and usage traces from browsers and apps.
File Shredder securely deletes sensitive files so they cannot be recovered.
Startup Manager helps you control which apps start with Windows, reducing the attack surface.
2. Control Startup Programs and Background Tasks
Unnecessary background processes can introduce vulnerabilities or privacy risks.
Use Glary Utilities’ Startup Manager or Task Manager (Ctrl+Shift+Esc) to disable or delay unneeded startup apps.
3. Regularly Audit System Security
Create a monthly checklist:
Run Windows Security’s Full Scan.
Review Windows Event Viewer for suspicious activity.
Use Glary Utilities’ 1-Click Maintenance to clean privacy traces, invalid registry entries, and more.
What Advanced Techniques Should Experienced Users Consider?
1. Implement Software Restriction Policies
Use Local Group Policy Editor (gpedit.msc) to create software restriction or AppLocker policies, allowing only trusted applications to run.
This is especially useful for preventing malware and controlling what runs on your machine.
2. Use Virtualization for Isolation
For risky tasks or software testing, consider running inside a virtual machine (VM) using Hyper-V or VirtualBox. This keeps your main system safe from potential threats.
3. Enable Secure Boot and UEFI
In BIOS/UEFI settings, ensure Secure Boot is enabled. This prevents unauthorized operating systems or bootloaders from running on your PC.
Regularly Back Up Data
Even the most secure systems can fail. Schedule regular backups using Windows’ built-in Backup and Restore, File History, or third-party solutions. Keep offline copies of critical data.
Conclusion
Improving Windows security and privacy is an ongoing process, not a one-time task. By combining Windows’ built-in features, tweaking advanced settings, and leveraging tools like Glary Utilities, you can significantly reduce your risk and protect your digital life. Apply these steps methodically, and review your settings regularly to stay ahead of evolving threats. Remember: security is about layers—every enhancement adds another barrier between your data and attackers.
