• privatezilla

  13 2,562 3.1 C#

  👀👮🐢🔥Performs a privacy & security check of Windows 10

  

  Project mention: What privacy enhancment script/app for Windows 10 is recommended nowadays? | reddit.com/r/PrivacyGuides | 2022-07-20

  I would only feel comfortable suggesting Privatezilla because it is open source. With OO ShutUp10++ you are installing software that tampers with your system and there is no way to understand how it works or if it's doing anything malicious. Privatezilla is also still maintained, as a matter of fact, they just released a big update code named Pollux that integrates LoveWindowsAgain which is a Windows 11 utility to disable various stupid things in Windows 11. I would also recommend what u/domsch1988 suggested, and use winget to uninstall anything else you don't 100% need.
