我每次都第一时间更新，但这次我没有，哈。现在MS向INSIDER的用户提供了更正版。如果下载WIN 10不从官网下载，有可能会下载到有BUG的那版，要小心点。
Updated version of Windows 10 October 2018 Update released to Windows Insiders
Last week we paused the rollout of the Windows 10 October 2018 Update (version 1809) for all users as we investigated isolated reports of users missing files after updating. Given the serious nature of any data loss, we took the added precaution of pulling all 1809 media across all channels, including Windows Server 2019 and IoT equivalents. We intentionally start each feature update rollout slowly, closely monitoring feedback before offering the update more broadly. In this case the update was only available to those who manually clicked on “check for updates” in Windows settings. At just two days into the rollout when we paused, the number of customers taking the October 2018 Update was limited. While the reports of actual data loss are few (one one-hundredth of one percent of version 1809 installs), any data loss is serious.
