Thank you for setting us straight. But I would like to politely remind you that the beta period for Windows 10 was supposed to end last Summer, and Windows 10 is now supposed to be in general release. This kind of mess shouldn't be happening.
Those of us with longer memories remember that this is Microsoft standard procedure with its operating systems: beta test via the general public for at least a year, including taking liberties to break people's machines in the interest of getting the OS right. This happened with Win 2000 until the first or second SP, XP until the second SP, and Windows 7 was kind of an SP for Vista (plus allowing time for hardware and drivers to catch up).
The reason XP and 7 stick around is because they each have evolved into something solid and reliable, but they got that way through a painful first year or so, after which Microsoft stopped adding features and just stuck with fixing critical bugs. So, warts and all, XP and 7 are stable, and you can write software and drivers for them and pretty much count on them working into the foreseeable future.
With 10, however, Microsoft is not only chasing the desktop, but also this crazy goal of grabbing the phone and tablet market. So how long should the Windows community expect Windows 10 to re-arrange itself whenever Microsoft feels like it? Windows 10 Home Edition (and Pro? can't remember) is the first OS I know of that actually forces updates upon people, kind of like the androids turning red in "I, Robot". Sure, this eliminates the problem of users who stick with buggy, malware-prone versions so common with XP, but more thoughtful users (and IT managers) now have to consider whether 10 is going to render something unusable, literally overnight with a mandatory update. Microsoft is apparently aware of this problem, which is why they permit Enterprise users to shut off automatic updates.
But non-Enterprise users want a stable, reliable platform, too. Right now, that means sticking with 7. My guess is that's part of Microsoft's master plan, why 7 is still officially supported, whereas people with 10 are still considered "early adopters" who should expect to go along with all the updates and spyware intended to "improve the Windows 10 experience".
Would be nice to know when beta is really over, hopefully before 7 goes the way of XP.
