Microsoft Will Resume Pushing Windows 10 To Machines With Win7, 8.1 (computerworld.com)
LichtSpektren writes: After previously apologizing on October 16th for forcing Windows 10 on some users of Windows 7 and 8.1 via the Windows Update mechanism, Microsoft disabled the default update option for Windows 10, so that users eligible for the new OS would have to opt in manually. Gregg Keizer at ComputerWorld reports today that Microsoft will soon switch the default option back to "on" again, possibly as early as tomorrow's "Patch Tuesday" update. Users who do not want Windows 10 are strongly advised to turn off automatic updating to avoid accidentally installing the OS.
This is going to be fucking annoying, no question about it, as you'll be hit with dialogs assuming you want to install. But there's next to no chance you'll accidentally install Windows 10. There are too many things you need to confirm before the install starts for that to happen. Plus, there's an "Undo" option in Windows 10 itself that lets you revert.
It's still mindboggling stupid of Microsoft to do this, especially with the half-finished bug-ridden unresponsive crap that is Windows 10 in its current form, but no, "accidentally installing Windows 10" is just about impossible. Even the computer illiterate are going to know this is what they're doing, even if they don't necessarily know the full ramifications.
You are not alone. This is not normal. None of this is normal.
