Is the November Threshold 2 update out for Windows 10 yet?

Episode 1249
Paul fromPaul has been waiting for the November update for WIndows 10. He's been waiting to upgrade. Leo says that SP 1, aka "Threshold 2" is out now, so he can upgrade for free and get the November update. Paul wants to know what he can do if he doesn't like Windows 10, though. Leo says that Microsoft gives him 30 days to roll back, but often the roll back button doesn't work. So having his own copy of WIndows 7 to roll back himself would be best. But Leo says he likes it and if he gives it time, he'll probably like it as well.
