Blackbird is a free utility designed to alleviate spending hours on tweaking your privacy settings using some known and less-known techniques to fully disarm Windows without leaving behind even the smallest possible footprint.

Other tools claim to block Windows from spying, but they are cumbersome to use and not as powerful or limited in scope. So the author took Windows apart, piece by piece, analyzed web traffic, system calls, file changes, etc., compared different configurations, designed and built a stand-alone tool, and spent hundreds of hours on beta testing so anyone can use it and it gets the job done right.

Block Windows spyware, on both the application and network level, with dynamic filtering without editing the HOSTS file or firewall settings and preventing diagnostic, password, contact, URL, SMS, handwriting, location, and P2P-update sharing.



Updated frequently and regularly; as long as Windows gets updates, so will Blackbird.
