Update: Microsoft has now removed the download links to the support page for the "Day One" Xbox One update. According to a statement from Microsoft sent to XboxOneDaily, "The site was not an alternative way to take the Day One update and customers still need to connect to Xbox Live for the update. Because of the complexity of this customer support process we’ve actually removed the page and we will work with customers directly to make sure they have a smooth experience."
Original Story: As we have previously reported, anyone who buys the Xbox One on launch day will have to install a "Day One" patch to enable all of the features. However, it's also likely that there will be lots of people downloading that "Day One" patch from Microsoft's servers at the same time, and as a result there could be delays in obtaining the update.
Microsoft has now offered a way for Xbox One owners to download the "Day One" patch ahead the launch. A Microsoft support page has the details on what Microsoft is calling its "emergency offline update", in case owners are unable to connect their new consoles to Xbox Live.
The process has three steps. In very basic terms, the first step is to find out which version of the Xbox One OS is installed on your console. The second step is to download the "Day One" update to a PC (download links are available on the support page) and place that update on a USB flash drive that has 2GB of free storage and has been formatted to NTFS. Finally, the third step is to connect the flash drive to one of the Xbox One's USB ports and follow the steps to install the update.
This is welcome news for anyone who knows they will be getting an Xbox One on launch day and we highly recommend those people to take advantage of this opportunity.
