I'm sure this is intended to block software thst could do things like remove Copilot and all the OS level advertising they keep populating windows with.
I tried the Official Windows 11 start menu. I had disabled showing "recommended apps" in the settings. This hid the icons, but not the section. So, whenever I opened the start menu, the entire bottom half was a section that said "enable recommended apps to show them here."
That's when I installed Start11 (I also bought StartAllBack, but I preferred Start11) and never looked back.
At this point I've just abandoned the start menu all together. PowerToys Run has effectively become how I launch anything that isn't on the taskbar, tied to one of the buttons on my mouse or a keyboard shortcut. Everything search on a different shortcut replaces the built-in search.
Of course that's just how I cope on my mandatory-Windows 11 work laptop. At home (and I know this is almost a meme at this point), I'm slowly getting myself accustomed to Linux alongside Windows 10 until that's no longer feasible.
