Microsoft has stopped distributing its latest Windows 10 October 2018 Update. The software giant started rolling out the update during the company’s Surface event earlier this week, but some Windows 10 immediately noticed their documents were being deleted. “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.

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.” It’s not clear how many Windows 10 users are affected by the problem, but even if it’s a small percentage it’s still surprising this issue was never picked up during Microsoft’s vast testing of the October update.
