@ Paul 87
Does the "average" PC user have a clue about privacy? They endlessly blab intimate details of their lives on Facebook and Twitter and upload stupid videos of themselves to YouTube.
They will LOVE Cortana and the "convenience" afforded by the Microsoft account. They don't comprehend that the same technology that gives them access to everything from one location also grants Microsoft the same access. Don't even try to tell them that it should be named "Windows 1984."
On a completely different note, after reading how to rollback, I did test upgrades on two computers. The old laptop has X1250 graphics, and the desktop has HD 5450. In each case, the Win10 Pro upgrade only loaded the default VGA driver, giving me only two choices -- 1024x768 and 800x600. Epic fail!
Hell, I'm 71 years of age. Windows 7 support might outlive me!
