Q. Is this really as harmful as you think?
A. Go to your parents house, your grandparents house etc and look at their Windows PC, look at the installed software in the past year, and try to use the device. Run some antivirus scans. There’s no way this implementation doesn’t end in tears — there’s a reason there’s a trillion dollar security industry, and that most problems revolve around malware and endpoints.
Now, it’s possible things have changed in the last few days, but I wouldn’t really expect them to based on the last time I used windows. I also didn’t know this before I tried looking it up, so I’ll admit I’m a little biased against microsoft.
But the real question is, what documentation are you looking at where you’re pulling all this information from? Can you provide a link?
