privatezilla VS WindowsSpyBlocker

I recently used Privatezilla to disable automatic updates. Not sure if the same approach works on Windows 11, but you might find the relevant registry keys mentioned in the code helpful: https://github.com/builtbybel/privatezilla/blob/master/src/P...

Privatezilla = Is an open source alternative to ShutUp 10, but be careful what you enable/disable. It has options that will impede functionality.

PrivateZilla will do all of this for you.

For all the things you might indeed want to do there are about a billion open source programs where you at least have the ability to see what they do. (For example.) Arium is a black box, you have no actual idea what they changed and most people just blindly trust that stuff without verifying (which again you don't actually can't do, at least not completely).

https://github.com/builtbybel/privatezilla is good. There's also ThisIsWin11 by the same dev for Windows 11.

Windows Spy Blocker = This will add a bunch of Windows IP addresses to your Windows Firewall. The basic settings should not impede functionality. It should also allow you to switch ntp (how Windows sets it's Clock) to more open alternatives.

Telemetry is similar to Windows 10. However, you can stop most or all of this with the hosts file or a Pihole. Add this: https://github.com/crazy-max/WindowsSpyBlocker/tree/master/data/hosts

You can use WindowsSpyBlocker on Windows to change the NCSI, or you can change it yourself

Also, the New Oil recommends WindowsSpyBlocker so that may be another option for you.
