Kinda reminds one of that "Free Vacation" you "win"-- IRL. as in "Yeah, Sure.."
Oh, once in a while they're for real but most of the time? Well as they say "no such thing as a free lunch!"
@ the oracle dude (too long a name to copy) Win 7 the latest you can stand? Ditto here. But take heart, it's why they're rolling out Windows 10 this summer-- or early Fall.
"8" is officially a bust . In spite of it emulating Smartphones which many (but not everyone) is so adept at-- that finger-swiping interface simply didn't "click" with many.
"10" is supposed to resemble "7" more than "8".
(But don't quote me verbatim.. in my line of work I deal with commercial and corporate clients who just last year gave up XP for Win 7 "Enterprise"- For many it was a large and costly undertaking, so I don't expect to be dealing with Win 10 issues on a professional level for.. years to come. Best to look it up via official channels.)
