Blackbird was designed to alleviate spending hours on tweaking your privacy settings by using some known and less-known techniques to fully disarm Windows without leaving behind even the smallest possible footprint. Don't want Windows spying on your every move? Don't feel like spending hours messing with privacy settings that ultimately still result in data collection? Think your private information belongs to you and no one else? Or maybe you just want a faster PC and don't like all the new "features" Windows has to offer.

Block Windows spyware, on both the application and network level, without editing the HOSTS file or firewall settings and remove all Windows telemetry updates. Prevent diagnostic data, passwords, contacts, URL, SMS, handwritting, location, and P2P-update sharing. Remove unique ad-ID tracking token and built-in advertising. Block Win10 upgrade (GWX) messages on Windows 7/8 and remove downloaded Win10 pre-install files/folders.
Prevent your PC from auto-installing Windows 10 while you're not looking. No installation, with a focus on leaving the smallest possible footprint, Blackbird is a single, portable exe with granular switches available. Want to restore everything back? We got you covered. Blackbird is regularly updated with new features and whenever critical Windows updates get released.
