Thoughts on Securing a New Windows Laptop for Privacy

I came across a question the other day about securing a brand new Windows 11 laptop with privacy in mind. The user was looking for advice on how to minimize data collection by Microsoft and maximize their control over their device. This got me thinking about the different levels of privacy you can achieve with Windows 11, and what steps are truly effective.

Let's break down some strategies for locking down a new Windows 11 laptop and keeping your data out of the wrong hands.

The Core Problem: Windows 11 and Privacy

Windows 11, like its predecessors, collects a significant amount of data by default. This includes telemetry data, usage statistics, and even browsing history if you're not careful. Microsoft claims this data is used to improve the operating system and personalize the user experience, but many users are understandably uncomfortable with the extent of the collection.

The key challenge is balancing usability with privacy. Completely locking down Windows 11 might make it unusable for some people. So, it's about finding the right balance for your specific needs and threat model.

First Steps: Local Account and OOBE Customization

The first and most crucial step is to avoid using a Microsoft account to log into the laptop. The user in question was already planning to do this, which is excellent. A local account significantly reduces the amount of data Microsoft can directly tie to your identity.

During the initial setup (Out-of-Box Experience or OOBE), pay very close attention to the privacy settings. Windows 11 will ask you a series of questions about data collection, location services, advertising ID, and more. Disable everything that you're not comfortable with.

Here's a checklist of settings to consider disabling during OOBE:

• Location Services: Unless you specifically need location-based features, turn this off.
• Diagnostic Data: Set this to "Required diagnostic data" instead of "Optional diagnostic data." This limits the amount of telemetry data sent to Microsoft.
• Tailored Experiences: Disable this to prevent Microsoft from using your diagnostic data to personalize ads and recommendations.
• Advertising ID: Turn this off to limit ad tracking across apps.
• Speech Recognition: If you don't use voice commands, disable this to prevent Windows from listening to your audio.

Beyond OOBE: Deep Dive into Settings

After the initial setup, there are many more privacy settings to configure within Windows 11. Don't skip this step! This is where you can really fine-tune your privacy settings.

Privacy & Security Settings

• General: Disable "Show me suggested content in the Settings app." This prevents Microsoft from displaying ads and recommendations within the Settings app itself.
• Speech: Review and disable online speech recognition if you're not using voice commands.
• Inking & Typing Personalization: Turn this off to prevent Windows from learning your typing habits and handwriting.
• Diagnostics & Feedback: As mentioned earlier, set diagnostic data to "Required" and disable "Improve inking and typing recognition" and "Tailored experiences."
• Activity History: Clear your activity history and disable "Store my activity history on this device" and "Send my activity history to Microsoft."
• Location: Review which apps have access to your location and disable access for those that don't need it.
• Camera & Microphone: Similarly, review which apps have access to your camera and microphone and disable access for those that don't need it. Pay close attention to background apps.
• Notifications: Disable notifications from apps that you don't want to be bothered by. This can also reduce the amount of data these apps collect in the background.

Account Settings

• Your Info: Make sure your Microsoft account (if you accidentally signed in with one) is disconnected and you're using a local account.
• Email & Accounts: Remove any unnecessary accounts that are linked to your device.
• Sign-in Options: Consider using a PIN or password for added security. Disable Windows Hello if you're not comfortable with biometric authentication.

System Settings

• Clipboard: Clear your clipboard history and disable "Sync across devices" if you don't need to sync your clipboard across multiple devices.

Network Privacy: DNS and VPNs

Windows 11's built-in privacy settings are a good start, but they don't address network-level privacy. Your internet service provider (ISP) can still track your browsing activity, and websites can still track you using cookies and other tracking technologies.

This is where DNS-based ad blocking and VPNs come into play. As we often discuss, DNS-based ad blocking can block ads and trackers at the network level, preventing them from ever reaching your device. A VPN encrypts your internet traffic and routes it through a server in a different location, masking your IP address and making it more difficult to track your online activity.

DNS-Based Ad Blocking (Our Recommendation)

As we always advocate, using a DNS-based ad blocker is a simple and effective way to improve your privacy. Here are a few options:

• NextDNS: Offers highly customizable blocklists, detailed analytics, and multiple device support. A great choice for power users who want maximum control.
• AdGuard DNS: Easy to set up and use, with good default blocklists. A good option for beginners.
• Cloudflare 1.1.1.1: Fast and privacy-focused, but doesn't block ads by default unless you use the "1.1.1.1 for Families" version.

To configure DNS settings in Windows 11:

1. Go to Settings > Network & Internet > Wi-Fi (or Ethernet, depending on your connection).
2. Click on your network connection.
3. Under "DNS server assignment," click "Edit."
4. Select "Manual" from the dropdown menu.
5. Enter the IPv4 and IPv6 addresses for your chosen DNS provider.
6. Save your changes.

VPNs

A VPN can provide an additional layer of privacy by encrypting your internet traffic and masking your IP address. However, it's important to choose a reputable VPN provider that doesn't log your activity.

Some popular VPN options include:

• ProtonVPN: A privacy-focused VPN provider based in Switzerland.
• NordVPN: A well-known VPN provider with a large server network.
• ExpressVPN: Another popular VPN provider with a reputation for speed and reliability.

Keep in mind that using a VPN can slow down your internet speed, so it's important to choose a provider with fast servers.

Browser Privacy: Extensions and Settings

Your web browser is another potential source of privacy leaks. It's important to configure your browser settings and install privacy-enhancing extensions to protect your data.

Browser Settings

• Privacy & Security: In your browser settings, disable third-party cookies, enable "Do Not Track," and clear your browsing history regularly.
• Search Engine: Consider using a privacy-focused search engine like DuckDuckGo, which doesn't track your searches.
• Permissions: Review which websites have access to your location, camera, microphone, and other permissions, and revoke access for those that don't need it.

Browser Extensions

• uBlock Origin: An efficient and open-source ad blocker that blocks ads, trackers, and malware.
• Privacy Badger: Automatically learns to block trackers based on their behavior.
• HTTPS Everywhere: Encrypts your communication with websites whenever possible.
• NoScript: Blocks JavaScript execution by default, which can prevent many types of tracking. However, it can also break some websites.

Removing Bloatware

New laptops often come pre-installed with bloatware, which are unnecessary apps that can slow down your system and collect your data. It's a good idea to remove any bloatware that you don't need.

You can uninstall apps from the Settings app or using a third-party uninstaller tool. Be careful not to uninstall any essential system apps.

Auditing Installed Applications

Take the time to review all installed applications, not just pre-installed ones. Look for any applications that you don't recognize or no longer use. Research their purpose online and uninstall them if they are unnecessary or potentially harmful. Some applications may run in the background and collect data without your knowledge.

Considering Linux

The user in the original question mentioned the possibility of switching to a Linux distribution. This is definitely an option for those who are serious about privacy. Linux distributions like Ubuntu, Fedora, and Debian are open-source and offer much more control over your system than Windows.

Switching to Linux requires some technical knowledge, but there are many resources available online to help you get started. It's a great option for those who want maximum privacy and control over their operating system.

Staying Updated

Privacy is an ongoing process, not a one-time setup. It's important to stay updated on the latest privacy threats and best practices. Regularly review your privacy settings, update your software, and be careful about what information you share online.

Microsoft also releases updates to Windows 11 that can sometimes reset privacy settings. It's a good idea to periodically review your settings after major updates to make sure they're still configured the way you want them.

Final Thoughts

Securing a new Windows 11 laptop for privacy requires a multi-layered approach. Start with the basics, like using a local account and configuring the privacy settings during OOBE. Then, dive deeper into the settings app, configure your network settings, and install privacy-enhancing browser extensions. Consider removing bloatware and auditing installed applications. And, if you're serious about privacy, consider switching to Linux.

Remember, there's no such thing as perfect privacy. But by taking these steps, you can significantly reduce the amount of data that Microsoft and other companies collect about you. The best approach is to stay informed, be proactive, and constantly adapt your privacy settings to the evolving threat landscape.
