UPDATE (Nov 24th, 8pm ET): As I was informed, both on Twitter and in the comments, the update has been restored. Apparently the issue was that this tool, when upgrading Windows 10 to Windows 10 1511, accidentally reset four privacy settings to default. They also happened to be four of the less-severe ones, such as whether to allow apps to run in the background and whether settings should sync between devices. It has apparently been fixed and the tool will install the latest version of Windows 10 once more.

Regardless of your opinion about Windows 10, I'm glad that Microsoft has once again provided a way to force a specific version on your device. Their recent statement, telling users that Windows Update will give them the correct build eventually, is not comforting if someone is failing to receive the update. Is it coming? Or did it block for some reason? I also wonder if the 30-day policy would still be enforced, making clean installs that much more annoying. Turns out it was all hypothetical, and Microsoft was planning on reinstating it instantly, though.
This is a bit surprising and disappointing. When the November 2015 update for Windows 10 went live, existing users could upgrade with Windows Update (if it let them) and the rest could force an in-place upgrade from Windows 7, 8.x, and earlier builds of Windows 10 using the tool. The latter method has apparently been reverted to the original Windows 10 build from July 2015.
This image is getting a lot more use than I intended.
Why? Who knows. They are still offering the update through Windows Update, and Microsoft claims that they have no intention of pulling it. This concerns me, because there are a few situations where Windows 10 updates will get stuck, such as if you get it through Windows Update then uninstall it. I have not seen any report cover the official procedure for this issue. Also, I wonder if there's a way to get past Microsoft's 30-day no-update policy.
According to WinBeta, Microsoft's official statement contains the following: “Microsoft has not pulled the Windows 10 November 10 update. The company is rolling out the November update over time – if you don’t see it in Windows Update, you will see it soon.” (Emphasis not mine.)
We'll probably hear more about this as the week goes on.
