Which org in MS is it that is so consistently failing its users in this way? Is it just Windows, or is it a separate org that's polluting Windows? I've not used Windows full time since Vista, but each time I dip in it's shocking to see how much bloatware there is in a default Windows install (not from an OEM) – adverts, pop-ups, casino games, celebrity news. Windows itself feels better, it doesn't take much digging to find a screen that hasn't changed since XP, but it's mostly nice on top. Is the crap from Windows itself? From a marketing team running amok? Is it all driven by Bing or Edge? Bing has always felt similar, like the MSN leadership were told to be more googley, but old habits have stuck around.
