Windows is easier to maintain privacy if you know how. There are tools that’ll disable most of the privacy issues in windows tool like Tidyos and SophiApp however I really recommend doing homework, look at all of the windows services and logs that a forensic examiner would look at and disable them, things like event logs, search index, shellbags, disable the jump list, if you look up my GitHub sunder the same username, I have a privacy guide aimed at windows users.
Also I recommend using something like Privizer or R-Wipe and wipe history each time you finished using your pc. One is free with a donors version the other one is paid but do a really good job of scrubbing history. I’d also set my browser to not remember history and look up the many privacy adons such as anti fingerprinting.
I also have a bootable usb handy to securely wipe drives in case I sell them when I upgrade them, it’s set to read only so no virus could ever infect it.
Keeping up to date on privacy, computer forensics and cyber security is a good practice. If someone stole or hacked my windows system they’d gain nothing of value from it as it’s basically programmed to never remember anything I do, not even the programs I run or the devices I plug in.
Never store credentials on the os, use FDE full disk encryption when possible but not bit locker as it’s a poor Microsoft product and probably has a backdoor according to news articles I’ve looked in to.
