Microsoft's Windows 10 October 2018 Update (version 1809) is now rolling out to general users. However, the early stages of the build are less than smooth and seem buggy. The latest issue with the platform is the update process wiping out important data. It is worth noting immediately that this is a problem that only affects manual downloads. If you receive the Windows 10 October 2018 Update automatically, you should be fine. In terms of the issue, users are reporting the update is removing data. Interestingly, it seems to be wiping personal data such as images, documents, and installed programs. It seems the October 2018 Update is messing up how it interacts with the Windows.old folder. This is where an update sometimes moves a previous installation backup. Users report personal files seem to be removed instead of passing to Windows.old. There are some things to remember. In general, we advise against updating a new Windows 10 build this early in its life, especially if you have a business. Most companies will wait for the platform to stabilize, while most individual users will wait for Microsoft's automatic update. Also, this just shows how important it is to backup Windows 10 before performing a manual update.
