I also agree that many people will be upset by Windows 10, and the changes in Windows 7, if they aren't already. I do have a tablet with Windows 10, and I will never make a purchase on that machine. Online businesses should listen up. I WILL NOT MAKE A PURCHASE FROM A WINDOWS 10 MACHINE **EVER**
The risk of using my CC number and having it end up in some Microsoft database is far too great. And Microsoft doesn't say they will definitely remove that information when they get it (they admit they will get it, though they claim that's "inadvertent"), they say they will do so "if they detect it."
So the simplest solution for them to avoid responsibility is to fail to detect it. As a result, when they have data breaches, they will not need to inform anyone because the CC number wasn't supposed to be in there. But criminal actors now have a new way of getting that data, along with my name, email, and who knows what else.
I also notice they didn't mention medical information at all (in their whitepaper referenced in this thread).
When my Windows 7 computer "dies" I will buy a Mac. I've had enough. I don't think Linux will ever be ready. I've been looking at Linux since 1991, and it has never been ready. They still claim they don't need Antivirus. Ha! Honestly, I didn't mind Microsoft so much when Bill Gates was at the helm, I think it has steadily gone downhill since he left. The company may have been greedy before, but the current behavior makes his misdeeds seem tame. I am actually wishing he'd return and kick some butt. I trust him more than the current establishment.
I don't buy the party line that they're using this information only to improve the product. They have mountains of data from users complaints all over the internet that would tell them what users want. Data gathering from forum posts would get them father than this scheme. At least if their stated purpose is honest. If not, then they're just gathering valuable database information and giving themselves a reason to avoid responsibility if the data is leaked.
While "moved cheese" is always annoying, the part of Windows 10 that bothers me most, and actually angers me beyond simple annoyance is the privacy issue. I hope it is challenged in court ASAP. Starting with the inability of most users to remove Cortana/Store or disable it. Even Android makes it possible to opt out of the Store, just don't set it up, the phone and all functions work fine. You get no such choice with Windows 10. I had to devote a lot of time into finding a fix that worked to remove Cortana and I'm honestly afraid to share it lest the ability to do that should be defeated. That fear itself speaks volumes for the future of Microsoft products.
