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.
This doesn't work for most streaming services. The ads and the actual video come from the same server. I know this is the case on Hulu (probably YouTube, too).
This is why I use Start11
