No iOS v26.2 update offer in my updated 64-bit W10's iTunes

My old iPhone 12 mini is currently at v18.7.2. My old, updated 64-bit W10 Pro. PC’s iTunes doesn’t even give me v26.2 in it when it is connected via USB cable. How come it doesn’t offer it Do I really have to get it in my iPhone?

Thank you for reading and hopefully answer soon.

Are you talking about Windows 10?

Why would you prefer to update an iPhone via an old version of Windows rather than directly? I can’t imagine that Apple tested Windows nearly as thoroughly as direct updates.
