If this happened to thousands/millions of business users during the work day, just think of all the lost productivity. I hope MS is sued into bankruptcy.
Most businesses of size internally manage their patching. They don’t rely on “Automatic Updates”. The problem with Win-10 Enterprise is that Microsoft intrudes into that area to an unprecedented degree preventing companies from “ala carte” installations of only the patches they believe they need. They’re using the stick approach with corporate America too (IMO a huge mistake).
