My "fuck up" was a Finding Dory ad on my lock screen. In OS advertising is a non-starter. I let the start menu ad's slide in 8, but that was the last straw for me. That and it bugging me "Edge is faster, Edge is better, use Edge!".
I feel like paid $199 just so Microsoft can sell me to advertisers. Bill never would of stood for this shit.
With OEM Windows, everything can be expected, from bloatware "drivers" slowing down your machine by half to obligatory root certificates (thanks Lenovo! thanks DELL!) that are necessary to serve you in-browser ads. And you're not theoretically allowed to remove them or it voids you warranty. So an ad at startup doesn't surprise me, it's not really Microsoft's fault, but that's what you get with a Windows OS.
