I am not arguing about any of these points, 64-bit is better in every aspect. I am just saying there are still a ton of PCs with CPU which doesn't support 64-bit OS. If they can have another alternative to Chrome then why shouldn't MS support 32 bit? At least till 32 bit versions of Windows is supported.A 64-bit OS and Apps are just better in terms of everything.

In my opinion, for consumers, Windows 10 Home & Pro should be 64-bit only, but Microsoft won't drop 32-bit Windows for some reason. In contrast Apple's macOS Mojave is the last version to support 32-bit apps, and iOS 11 dropped 32-bit app support in 2017.
