privatezilla

Privatezilla is a Windows 10 tool that checks and adjusts privacy and security settings on your computer. Windows 10 ships with a number of settings related to data collection, telemetry, and background services, and many users are not aware of what those settings are or how to change them. Privatezilla collects 60 of the most relevant ones into a single place, shows you which are active and which are not, and lets you toggle them on or off.

The interface shows each setting with a status of either "Configured" or "Not configured." Configured means the setting is in a privacy-protective state. Not configured means it is left at its default, which may send data to Microsoft or enable features you might prefer to turn off. The tool is designed to be fast to use: open it, review the list, and make your choices.

For users who want to go further, there is a separate community package that adds PowerShell scripting support. This optional add-on can do things like remove pre-installed apps that came with Windows, uninstall OneDrive, remove Start menu tiles, and disable telemetry in third-party programs like Firefox, Dropbox, and CCleaner. It also includes rules for blocking tracking traffic at the firewall level and through the system hosts file, using lists maintained by an outside project. This community package is labeled as being for advanced users only.

The tool only supports Windows 10, specifically versions 1809 through 2009. It does not mention support for Windows 11. Installation is a simple download from the GitHub releases page with no additional setup steps described beyond that.

Privatezilla is a free, open-source project maintained by a single developer. Donations are accepted via PayPal.
