Wifes cpu would not upgrade to win10.
Changed the HD, upgraded just fine, from win 7 beginner.
Personally, I think that mocking people for having privacy concerns deeper than one's own is out of line. In what way is it harming you or anyone else if someone else prefers not to have their private information tracked?
@alphanumeric and @frankenhooker - Thanks for the details. I did not read those details on my PC when I turned off that option. The font wasn't clear and I did not want to read a lot! But yes, I see now. They can send updates down to other devices on your own network or to other PC across internet.
I think this should all be a part of the initial set-up process, where the user gets to choose all such settings. It would be the ideal way, rather than people discovering over the internet, etc. Some people may not even know it unless they explicitly searched for it on internet.
For myself, I found out this setting, when I read on the internet that updates would automatically be downloaded and bandwidth would be consumed, unless I switch these settings. I have a metered internet connection, so this could have been dangerous. It will still be dangerous for millions of "general users" across the world, who would use a PC as PC and are not "tech savvy"
So yes, agreed, it is dangerous.
