Here are the results of my “exploring”:
I started with WPD. Even though its last update date is in 2021, it can uninstall bloatware like the game bar, anything xbox related or anything else you don’t want, which O&O ShutUp++ doesn’t do.
I then used O&O Shutup10++ and it worked great. It has a clean interface and explains each toggle clearly. Thanks @Dkama as well. It isn’t open source, so there is always a risk, but it all comes down to trust in the end. Do I trust more a random person who made a software with privacy in mind vs Microsoft? Unfortunately, the answer is yes.
Fortunately, privacy.sexy exists. I tried it, which is similar to O&O Shutup10++, but Privacy.sexy seems even more complete and the description of each toggle is really thorough. Since privacy.sexy is open-source and seems more complete then the other two, using a combination of programs seem redundant. I would recommend only this one. It takes some time to read what each action does (and you really should because it will break things if you apply some stricter rules), but at least, you are in control of what you need. It also can remove bloatware. I feel like people saying “using this software provides a false sense of privacy/security” haven’t actually looked at the scripts.
Finally, I tried WindowsSpyBlocker. I only added the recommended “spy rules”. I didn’t touch anything as I had no idea what I was doing.
