The software giant intended to push the update to all Windows 10 users next Tuesday, but it looks like this will be delayed until Microsoft is sure that its update will not result in data deletion. At the moment, it's not clear what's causing the issue, nor do we know how widespread it is.
We have paused the rollout of the Windows 10 October 2018 Update (version 1809) for all users as we investigate isolated reports of users missing some files after updating,” says Microsoft on its support site for Windows Update.Via: The Verge
Microsoft is now recommending that affected users contact the company directly, and if you’ve manually downloaded the October update then “please don’t install it and wait until new media is available.” Other Windows 10 users have been complaining that the Microsoft Edge browser and other store apps have been unable to connect to the internet after the October 2018 Update, and the update was even blocked on certain PCs due to Intel driver incompatibilities.
