Why does every printer I’ve had or used, with any version of Windows, stop connecting after a while and need setting up again ? (We even get this at work with networked printers)

Is it printer support in Windows being overly complex? Poor printer drivers? Poor printer firmware ?

According to a comment by the OP:

So the difference is:

Internet Explorer in this build is still alive.

There are some tiny differences on system taskbar icons(such as Search, Start menu) The task view in this build is like Win10+Win11

Dark mode has outlines

There's a code on the background

Unlike current Win11, TPM and Secure boot and etc requirements are not needed

I've recently discovered a new mail client, which is free on the Microsoft Store.

It looks very aesthetically pleasing, and could be a promising project to follow!
