Actually, that clears things up rather nicely. In essence:
- Windows 7 and 8.1 users get their free upgrade, no strings attached.
- People who installed the Windows 10 Beta and agree to remain opted in to updates will continue to get Windows 10 updates indefinitely, so they get Windows 10 for free as well. The proviso here is that they have to stay opted in for updates, otherwise they lose that license.
In short, anyone who thought they could just get rid of XP and get Windows 10 free will actually get Windows 10 free, but with the provision that they're essentially "renting" the OS in perpetuity unless they buy a real license.
To me, that sounds pretty fair.
Still not a fan of it. I'm afraid that if I try to upgrade myself from 7 that I'll screw it up. It'll literally be my first time. Not to mention the rest I'm not thrilled with in regards to 10.
Hence me waiting. Will be backing up ahead of time to be on the safe side.
