You act as if the experience on Windows is the point of Apple's password manager. I'm not surprised the experience is pretty bad -- as far as I can tell, accessing the passwords and notes is pretty much the only thing you can really do on Windows, and the user experience is significantly impaired compared to Apple devices.

(For example, it only stores the passwords in memory and never persists them locally in any form, because there's no way to secure that, so it has to redownload them from scratch every time you open the app. It also only supports proper Windows Hello PINs rather than normal account passwords, because that's the only way to get proper hardware backed cryptography locked behind authentication, etc. It's a mess)
