Microsoft to Offer Windows 10 .....for Free

I'm still looking for a catch but don't see one.

Funny thing is I've been reading on the net for 10 years that Microsoft is "EVIL!!!" so I wondering how a free upgrade will go over.

Microsoft Clears Up Just Who Gets Free Windows 10

Microsoft really wants people to upgrade to Windows 10 when it comes out this summer. So much that Microsoft announced at an event in January that upgrading to Windows 10 would be free for a year.
But then what?
I had a chance to sit down with Aaron Woodman, senior director of product marketing at Microsoft, to get the skinny on the “Free Windows 10” offer.
To recap what we’ve known since the Jan. 21 Windows 10 announcement: Microsoft will provide an upgrade from Windows 7 or Windows 8 to Windows 10 for free, for a period of one year from the release of Windows 10. There are some important details to this deal that were revealed, and a few that weren’t. In my talk with Woodman, I got what I think is the definitive take on who will have to pay for Windows 10 and when, and who will not. 

Versions you can upgrade from 

The Windows 10 upgrade will be free and a one-step process for consumers using the current versions of Windows 7 (SP1) and Windows 8 (8.1). If you’re using an older version (Windows 7 or Windows 8 proper), you’ll have to upgrade to the current version first. Those upgrades are free, too, but Windows 10 won’t upgrade Windows 7 or 8 until it’s made current. That’ll make the upgrade a two-step process for users on older versions.~snip~
