Microsoft is re-releasing its Windows 10 October 2018 Update today, following the company pulling it offline due to data deletion issues over the weekend. The software giant says there were only a few reports of data loss, at a rate of one one-hundredth of one percent. “We have fully investigated all reports of data loss, identified and fixed all known issues in the update, and conducted internal validation,” says Microsoft’s John Cable, director of program management for Windows Servicing and Delivery.

Microsoft is now re-releasing the Windows 10 October 2018 Update to Windows Insiders, before rolling it out more broadly to consumers. “We will carefully study the results, feedback, and diagnostic data from our Insiders before taking additional steps towards re-releasing more broadly,” explains Cable.
