Ah, now I understand the question. I've never seen anyone use WOS instead of just Win10 or Win11. 🙄
Win11 is inescapable on platforms capable of supporting it for two reasons...
Win10 reaches end of life in October 2025 and you'll have to pay to receive updates after that date.
Windows, both 10 and 11, are the property of Microsoft not you. You only pay for a license to run them. The EULA you explicitly accept at install time requires you to accept all updates that Microsoft issue, since it's their software. Upgrading a capable platform from Win10 to Win11 is simply one of those required updates.
