Microsoft pulled the Windows 10 November update downloads over the weekend. Asked whether or not this was due to reported technical issues, a company spokesperson told us, "We look into any issues our customers report and appreciate their feedback. We don't have any further information to share today."
Despite then declaring no more manual downloads the new policy, they have now been restored, so if you want to upgrade cleanly or manually as opposed to through Windows Update, you can. Here is the official statement:
"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."
ZDNet reports the aforementioned settings preferences were privacy related and were re-enabled after upgrading to the new build for those who had previously disabled them, making this a sensitive legal issue. Those settings will now be restored as normal courtesy of a new cumulative update, for anyone affected.
