Microsoft has restored all downloads with an updated build, Windows 10 build 10586.14. Earlier, the company had rolled out all ISO images and Media Creation Tool of the TH2 update and then pulled them abruptly. Now, everything has been returned however this shows the fragile nature of the rapid release development lifecycle where serious untested bugs can crop in.
Microsoft explained that the previous release had a bug:
Recently we learned of an issue that could have impacted an extremely small number of people who had already installed Windows 10 and applied the November update. Once these customers installed the November update, a few of their settings preferences may have inadvertently not been retained. For these customers, we will restore their settings over the coming days and we apologize for the inconvenience. We worked to resolve the issue as quickly as possible - it will not impact future installs of the November update, which is available today.
If you are interested in the details, the bug Microsoft fixed reset the following settings in the Privacy options of Windows 10:
- Sync with devices.
- Let apps use my advertising ID.
- Let apps run in the background.
- Turn on SmartScreen Filter for web content.
That's it. If you are using Windows 10 version 1511, it is a good idea to update it right now.
