Is it safe to install the October 2018 Update for Windows 10?


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.

You can follow the latest updates here.


Microsoft has confirmed that the October 2018 cumulative update KB4464330 fixes the file deletion problems.

The company is also issuing a new version, Windows 10 build 17763.17, that includes the fixes as well, but it’s currently only available for testers in the Slow and Release Preview ring of the Windows Insider Program.

However, it’s still not safe to install Windows 10 version 1809 (October 2018 Update) on your primary machine as the company has to test the fix and once it’s proven safe, it will re-release the update to the public.

The re-release date is yet to be announced.


If you’ve already installed the new version of Windows 10 and your files have been deleted as a result of the bug, the new update will resolve the issue, but it’ll NOT restore your files.

You will need to contact Microsoft directly at +1-800-MICROSOFT or find a local number in your area https://support.microsoft.com/en-us/help/4051701/global-customer-service-phone-numbers.

If you have access to a different computer, you can contact Microsoft at https://support.microsoft.com/en-us/contactus/ (the link will vary according to country of origin).

Important: Microsoft says that will help you free of charge, but the company "cannot guarantee the outcome of any file recovery work."


If you don’t want to deal with the Microsoft support, some users are recommending to use data recovery tools such as Recuva to get the files back.


Update October 21, 2018: It’s still not safe to install the Windows 10 October 2018 Update on your computer. However, Microsoft has been working hard to patch the most significant problems, and the re-release of the feature update is nearing.

Hopefully, it’ll happen before the end of October.


All updates are mandatory by default on Windows 10, but you can usethis guide to skip the a feature update.

Just keep in mind that new version of Windows 10 are only supported for at least 18 months, so eventually, you’ll need to upgrade.


Is it safe to upgrade as of right now?


No, it’s still not safe to upgrade to the October 2018 Update.


Is it more likely to be fixed by the end of this month or next month?


I’m really hoping to see the October 2018 Update re-releasing on October 30, so Microsoft can still use the same name.


Although there has been a number of updates, as of November 6, 2018, it’s still not safe to install the Windows 10 October 2018 Update (version 1809) on your computer.
