I installed a fresh copy of windows straight from the official ISO a month or two ago and was bombarded with candy crush, tiktok, CNN, instagram, LinkedIn, etc. It took me a few solid hours to get it out of my way as much as possible.
After that, even on my brand new Ryzen 9, it took 15 seconds to open a web browser. I decided to quit my windows-only games and delete windows in favor of Linux (like usual).
It's not just OEM installs, perhaps you got windows a few versions back and updated it avoiding the new bloatware crap.
