What is Bing?
It’s like google. A search engine.
Microsoft has a web browser called Bing, which also reports query metrics to third parties or via Microsoft.
Lots of horror stories with Bing and Cortana.
Fellow employee had his annual physical and before results were fully released, his doctor confided in him that there were indications he was developing Diabetes II.
He went to work the next day with his new cell phone while his coworker was installing Win10 and running it fr the first day and spoke with him that he might be getting diabetes II. The following day he started getting adware for diabetes II testing kits and medication.
The topic was only spoken of by his doctor and him and him to his coworker, verbally. Nothing searched by the people with the cellphones or the computers.
Bing will work with Cortana to turn on the cellphone or PC microphones periodically and search for different buzzwords into market analysis systems, forwarding your “input” for their marketing.
If you read the Microsoft licensing Agreement and the Microsoft Toolkits which are required to load the OEM version of the software by the terms of the licensing agreement, They are provided by first becoming a Microsoft Partner, then using their toolkits to install the software. Their default recommended installation includes installing Bing as your default browser. Once it’s on there, you can’t get it off, even if you re-image the OS (so it’s been reported).
