It seems simple enough: Install a new launcher on your Android phone, make a few configuration changes, and away you go. But using the Microsoft Launcher may require a few additional considerations. I consider this to be the line between what Microsoft wants and what you want.
Don't get me wrong: There's nothing malicious about Microsoft Launcher. And it absolutely gets better the more invested you are in the Microsoft ecosystem. But I don't approach this with a child-like "Microsoft knows best" worldview like we see on certain Redmond-obsessed tech enthusiast blogs. And neither should you.
