I want to poison as much of my online data as I can, and I know that companies can get it anyway if I delete it, but if I were to spam sheer volume, it would cost more than it’s worth to try and sort it.
Dad uses windows and the main device I use is his laptop, and I understand that Microsoft scrapes everything they can. He’s going to reset his laptop soon, so all the junk is erased, but would it be possible to temporarily poison most data on there (from ms perspective) until it’s reset?
Would it be possible to do that on other things too, say corporate owned software, social media, etc?


Don’t know how to do that, also sadly using windows.
I kinda know how to install pihole onto a computer, as in I ran the command on mint once, but I did it slightly wrong potentially
You can also use NextDNS which is kind of like a Pihole in the sky. Pretty easy to setup.
The OS you are using doesnt matter. I didnt follow a guide or else I’d link one for you but even with little knowledge it could very well be done. All you are doing after installing is changing 1 IP on your router’s DNS settings and setting a reservation for the pihole machine. Its practically setup at install. All I changed was blocking some extra microsoft stuff like their heartbeat monitor and setting my own DNS to Quad9. Might be worth it to look into if you are curious enough about privacy to poison your data.
Use adguard or nextdns for os wide protection and ublock for browser level protection. No selfhosting required.
