How much privacy could you get on a Windows 10 PC?

I switched to Linux Mint and it was too much for me because I don't have time to learn all these commands, I work as a video editor and I own a Davinci Resolve Studio license but it took me 5 hours to get it to work on Linux (they officially support Rocky Linux distro, not Mint).

Eventually I found a guy who made some script to make it work, so if this guy dies and Davinci Resolve gets an update, I'll be unemployed.

I heard a lot about Linux being "so customizable" but actually turned out to be way less customizable than windows. Yes I spent most of my time taking commands from chatgpt and pasting the errors I get back to chatgpt. I really underestimated how the system works.

I'm back on windows now, I'm having really hard time accepting this but I really need windows to put food on the table (I know I can dual boot but then what's the point). I use mullvad VPN, Firefox, DuckDuckGo search engine, O&O app buster, simplewall and ShutUp. I use protonmail for emails and I completely nuked OneDrive from my pc and using a local account.

Is there more that I can do? I'm becoming really obsessed with privacy to the point that it's annoying me, I was even looking how to become my own ISP lol. I removed 9 years of my photos from google photos and saved them on an external drive.
