I specifically despise Microsoft Accounts being forced down our throats because, among all other things, they make certain workflows impossible. For instance, you can't schedule tasks to run as your user when you're not logged in[1]. It won't work because your Microsoft account doesn't have a password in the traditional sense. You basically can't do anything that requires you to enter your Windows user credentials. I also had problems with making Remote Desktop connections to my other computers at home in the past and maybe it's related to this too.
Another thing; I don't like seeing multiple WebView-based apps running on my system all the time either. WebView or Electron screams lazy to me. Because some dev team didn't want to bother to write a decent and lightweight GUI frontend with numerous GUI frameworks Microsoft had released, 1.5 billion Windows users have to pay the price to have an extremely heavyweight layers of layers of abstractions on their system running all the time. I can't imagine the waste at this scale. Something basic like "Start menu search" should never be a WebView, but it is[2].
