You can actually use windows without an account. When installing windows, they will force you to log in. But If you simply use an account that has been blocked it will create a local user instead of an online user. People use no@thankyou.com and it works well
I deleted my Amazon account and swore never to order from them again, and so far that's been a effortless affair. Using smaller vendors and bookstores on principle makes me happy. I deleted my Microsoft account as well, but since I don't use Windows that was really more of a formality than anything else. Google I stopped using and am never signed in to, but I haven't deleted the account I opened in 2004, and I still fetch mail from it. I cleared all information from it that I could, and that'll have to be good enough for now. When it goes a year without receiving a meaningful message I will consider getting rid of it entirely.
Microsoft is already done same with google I have like one niche product that I have not found a place outside of lime a singular stellar on Amazon to buy from
