Unfortunately Microsoft are the ones who decided to make Windows 10 a free upgrade for Windows 7/8 users, so we all bear the awfulness of them needing to sell sponsored spots in the OS to compensate for that loss of revenue. At least if the OS basically makes money on its own on an ongoing basis, we won’t need to ever pay for Windows updates again? Still, ugh.
edit: I’m agreeing with you guys here. I’d spend more on an “ad-free” Windows license if I had a choice, but that doesn’t exist unless you’re a volume license customer (LTSC) I wish they’d find some way to let people avoid the ads, like having them in Home and disabling them in Pro, as most laptops (even my Dell XPS) ship with Home. (They did try “Windows 8.1 with Bing” once. I guess it didn’t work out?)
