MajorPrivacy is an advanced Windows privacy and system protection tool that gives you detailed control over what applications can access, where they can connect, and how they interact with your system. Made by Xanasoft , the maker of Sanboxie and Diskcryptor, it’s aimed at power users, security enthusiasts, and anyone who wants more visibility than the standard Windows security tools provide. If you've ever wondered what programs are doing behind the scenes, MajorPrivacy helps answer those questions.

What MajorPrivacy Does

MajorPrivacy combines application control, privacy management, network monitoring, file protection, and system hardening into a single interface. Developed as the successor to PrivateWin10, it goes well beyond simple privacy-tweak utilities by providing active monitoring and enforcement tools rather than simply changing a handful of Windows settings.

One of the standout differences is its use of kernel-level protection components. This allows the software to monitor processes, restrict file access, control network activity, and help prevent unwanted applications from running. The result feels more like a complete system control center than a traditional anti-telemetry utility.

Why Someone Would Use This Tool

Windows includes a decent collection of security features, but it does not always make it easy to see exactly what applications are doing. MajorPrivacy fills that gap by exposing activity that would otherwise remain hidden.

For example, if a newly installed application suddenly starts making network connections you were not expecting, MajorPrivacy can help identify where it is connecting and allow you to block or restrict that behavior. The same applies to programs that repeatedly access sensitive folders or launch background processes without obvious reasons.

For IT professionals and advanced home users, it can function as both a monitoring platform and an enforcement tool. The logging capabilities alone provide valuable insight into what is actually happening on your system instead of what software vendors claim is happening.

Useful Features Worth Knowing

One feature we particularly liked is the flexible installation process. The installer can perform a traditional installation or simply extract the files for portable use. That is useful if you want to test the software before committing to a full installation or deploy it across multiple systems without running the installer each time.

The ability to import and export rules is another welcome addition. After spending time creating application restrictions, network policies, and file access controls, being able to move those settings between systems can save a considerable amount of time.

The activity logging also deserves mention. During testing, it quickly became apparent just how much background activity many applications perform. Having all of that information available in one place makes troubleshooting and investigation far easier than digging through multiple Windows logs.

Another interesting feature is the ability to create and mount encrypted disk images. Think of these as virtual hard drives stored inside a single file. Once mounted, Windows treats the image like a normal drive, allowing you to store files inside it just as you would on any other disk.

This can be surprisingly useful for protecting sensitive documents, financial records, client files, or anything else you would rather keep separated from the rest of your system. When the encrypted image is dismounted, the contents remain inaccessible, providing an extra layer of protection beyond standard folder permissions.

It's not a feature everyone will use every day, but for privacy-conscious users, it is a welcome addition that eliminates the need for a separate encryption utility.

How to Use It

After installation, MajorPrivacy presents a collection of modules covering application control, network management, privacy settings, and monitoring tools.

The interface is one of the better-designed security utilities we've seen recently. Despite the huge number of options available, it rarely feels cluttered. Navigation is logical, and most sections are easy to locate once you've spent a few minutes exploring.

That said, some areas could benefit from additional explanations or configuration hints. New users may occasionally wonder exactly what a particular setting does before enabling it.

Fortunately, the built-in setup wizard helps smooth out the learning curve. It walks you through recommended settings and provides a much easier starting point than manually configuring every component yourself.

Before making major changes, we'd strongly recommend creating a System Restore point and backing up your registry. MajorPrivacy operates at a deep system level, and having a recovery option available is simply good practice whenever you're working with advanced security software.

Limitations or Downsides

The biggest challenge is complexity.

MajorPrivacy is designed for users who want deep control, and that naturally comes with a learning curve. While the interface is exceptionally polished and surprisingly approachable for such a powerful utility, some advanced settings could use additional documentation or contextual help.

Another point worth mentioning is licensing. Although MajorPrivacy is open source, some advanced functionality requires a registration key. New users can obtain a free key, but it expires after 90 days and must be renewed.

Users who support development through Patreon or PayPal can obtain a supporter key that provides ongoing access without the need for periodic renewals. Considering the amount of development involved in a project of this scope, that seems like a reasonable approach rather than a drawback. Frankly, I like it.

The good news is that personal licenses are not tied to a single computer. Home users can use the same license across all PCs they personally own, making the portable version much more practical than we initially assumed. Commercial users, however, are required to license each PC individually. The licensing model is similar to the one used by Sandboxie Plus.

Geek Verdict

MajorPrivacy is not another privacy tweaker that flips a few registry settings and disappears. It provides genuine visibility into what applications are doing and gives you the tools to control that behavior when necessary.

We especially liked the portable deployment option, rule import and export support, detailed monitoring capabilities, and the clean, modern interface. The setup wizard also makes the software more approachable than many competing security tools.

The tradeoff is complexity. This is not a utility you'll fully understand in five minutes, and some settings could benefit from additional guidance. The registration system may also raise questions for users expecting a completely unrestricted open-source experience.

Still, if you've outgrown basic privacy tools and want meaningful oversight of your Windows environment, MajorPrivacy is one of the most capable privacy and system control utilities currently available.
