Win11debloat solves 99% of annoyances with Windows 11 in <5 minutes. I’ve used in as the first step on every Win 11 install for years. It’s mostly just a bunch of Powershell commands disabling/configuring features.

Nothing has ever reverted after an update for me, so it’s a one-and-done thing. Ironically, afterwards Windows 11 has fewer noticeable ads than my MacBook which still continually pushes Apple services/shows/etc in settings/push notifications.

The only setting that I’ve ever seen sneakily disabled in recent years is the Edge default search engine but that's out-of-scope for Win11debloat.
