It crossed my mind too, after all I've read here over time.
Already I'm experiencing fresh problems on this PC: very slow startups and, most aggravating of all, a Start Menu button that stops working and won't function again without a restart. Looking online, loads of other people are experiencing this and they're all given elaborate instructions to 'correct' it, which I would contend even a lawyer would struggle to understand. But we shouldn't HAVE to put it right ourselves... there was no problem in Windows 8.
