In my case, I use the Chrome browser and had a specific set of pages set up, and also had a specific thing set to happen when I opened a new tab.
Without my having to respond to any specific queries in regard to changing those preferences so that Bing would open 1) as my front page, and 2) as the default "new tab", precisely those two changes were made. I want to emphasize that this happened without
any warning or querying for input on my part as the user.
I have been a windows user for many years, and it is only recently that this sort of thing has started happening. If it is somehow the result of automatic updating, then this is a new feature of automatic updating, and it should be changed - reverted back
to the old style of automatic updating that did not result in such invasive reconfiguration of daily use, browser preference settings.
I'm going into such detail here in the hope that people employed by Microsoft read the input / feedback in this forum.
The problem that I and others are discussing on this thread boils down to exactly one thing: poor quality customer service.
I am not a "hater." I very much prefer Microsoft products in general to competitors, but I do not like Bing. I use Google as a fully integrated set of tools, and I do this in part because my employer mandates it.
I implore any representative of Microsoft who may read this to understand that by attempting to "force" or "trick" users to change their browser preferences to adopt Bing, Microsoft engages in behavior that WILL turn users against their products. Again, if
you want users to adopt your product, create a good product and market it effectively instead of using sneaky, underhanded means to foist that product onto unsuspecting users.
