so I started to see stuff on O&O ShutUp10++ that help disable most intrusive windows features, but it's closed sorce, wondering if they are any open source alternatives? Shutup10 ++
I think the project has a better chance than most at being relevant long-term for a number of reasons, but also the maintainer is a pretty cool person!
Maybe try this PrivateZilla but it's always a great step to reduce even by a little your data leaks, but as some already said here you should consider switching to linux, even with all your efforts you cannot repair a broken thing at the base....
