We haven’t seen the worst of it. Most people won’t care about lack of security updates unless nagged by MS directly. What damages older platforms worse is incompatible apps, especially Chromium-based browsers and Electron-based apps, and therefore individual websites that block outdated versions.

If you are to join a chat with your boss in MS Teams, you need to make it work. That won’t fly on older versions of Win10, neither on previous OSes. But their service’s web version, probably limited, works as long as Firefox keeps working on aging systems, while Chrome gave up a long ago, and may abandon Win10 too if they’d like to.

When that would happen, when there would be a popular piece of software requiring a non-negotiable switch, that would pronounce Win10 a dying platform. That may be more of a streamlining choice on devs’ side rather than an obvious necessity, but who cares? If baby me had Steam or a favorite meme page stop working, I could’ve cried to my parents until they fix it with money.

Like in marketing, you don’t sell the product itself, you sell vibes, benefits of ownership, not wheels but miles. Win11 should become a choice of ultimate convinience, usability, comfort - compared to erroring out Win10 PCs. This needs enough momentum, and the end of Chromium on W10 is the best thing that would happen to modern MS targeting existing users.
