enterprise (and "pro for workstations") edition of windows 11 has little to no ads.
same applies to windows 10 pro or higher with local accounts
you should go with enterprise if you need windows for any reason anyway, as it's the only edition with an option to disable telemetry (set it to "Security" in group policy editor, in pro it only goes down to "Required", and no debloating tool will help with that) (it's impossible to do without partching the os or using a firewall in other editions, yes, Microsoft basically paywalls privacy)
ma account login can be blocked via a gpo in pro or higher editions, the system pretends they don't exist at all (e.g. add new account button brings up a menu to add a local account immediately)

Yeeeeeaaah I'm still not gonna use Windows. Thanks for the explanation tho! I did not know that there were substantial differences between the different versions.

Which a regular person can't buy.

The easiest legal route to a permanently debloated Windows with 10+ years of patches is Windows Server Essentials.
