Best answer: Yes, the problems have been fixed, and now the Windows 10 October 2018 Update is safe to install starting November 13, 2018, according to Microsoft.
Previous answer: No, it’s still not safe to install the Windows 10 October 2018 Update, at least until Microsoft resumes the rollout, which is currently paused.
The Windows 10 October 2018 Update (version 1809) was originally released on October 2, but because of a bug that caused data loss to several users, Microsoft was force to stop distributing the update.
As of October 9, there’s a new update that bumps the version number to build 17763.55, but Microsoft hasn’t clearly confirmed that the file deletion problem have been resolved, and users are still unable to download the ISO or Media Creation Tool to upgrade to version 1809, which indicates that the update is still not safe install.
