This is one of the use cases that motivated tag hierarchies. If we make `windows-10-21h1` a child of `windows-10`, then anybody searching for `windows-10` will also see the questions from child tags by default. (You can restrict it to show *only* the parent tag and not children if you want, though I'm not sure why you would.) Meanwhile, we can better characterize posts with more specific tags so you can more easily find them, and from a child tag page you can navigate to the parent tag. This doesn't apply to operating systems (I don't think), but we do need to keep in mind that hierarchies don't support multiple inheritance. If we wanted to have `ms-office` have child tags for `ms-word`, `outlook`, etc, then we couldn't *also* mix in version there without fragmenting the hierarchy. I mean, you could have `ms-office-2020` and its children, and `ms-office-2017` and its children, all be children of `ms-office`, but you *couldn't* then find all the Outlook questions regardless of version. So let's not do that.
