Microsoft's "Fix" for Windows 11: Flowers After the Beating
I admire your effort to increase user privacy but it's very difficult to argue that allowing a piece of proprietary closed-source software to make fundamental changes to your operating system is a good idea.
For starters, it doesn't explain what exactly it does. This is all I could see on the info page:
> Privacy Enablement Center: Politely ask already installed Windows 10/11 to phone home less, or add Privacy Enhancing DNS Proxy to already installed Windows, in order to block Telemetry, Windows Updates, OneDrive, builtin advertisements, tracking of your location and other types of potentially unwanted Windows network activity — making Windows 10/11 completely quiet online — something competitor’s tools can’t achieve.
That sounds an awful lot like using the hosts file or a firewall such as Portmaster[1] to block known tracking domains, no?
