How do you know the difference Actual question lol I’m not too sure how the whole thing works

If you’re referring to browsers, just take a look at your telemetry/data usage settings. Most common browsers take every single action you do a utilize for either your personalized ad portfolio or sometimes improving the program. I use LibreWolf because it comes with an Adblock and no telemetry.

Difference between what? Not to be rude but you’ll have to be more specific. I’ve been using Windows for over a decade and the quality of the OS has declined due in part to it trying to emulate macOS and or chrome/mobile OSs. They riddle the OS with ads and don’t put focus into performance.
