Microsoft says it has fixed the file deletion bug which affected Windows 10 version 1809 installs, and is pushing the update out to Windows Insiders before commencing a roll out to all.

Prior to re-releasing the October 2018 Update our engineering investigation determined that a very small number of users lost files during the October 2018 Update. This occurred if Known Folder Redirection (KFR) had been previously enabled, but files remain in the original “old” folder location vs being moved to the new, redirected location. KFR is the process of redirecting the known folders of Windows including Desktop, Documents, Pictures, Screenshots, Videos, Camera Roll, etc. from the default folder location, c:\users\username\<folder name>, to a new folder location. In previous feedback from the Windows 10 April 2018 Update, users with KFR reported an extra, empty copy of Known Folders on their device. Based on feedback from users, we introduced code in the October 2018 Update to remove these empty, duplicate known folders. That change, combined with another change to the update construction sequence, resulted in the deletion of the original “old” folder locations and their content, leaving only the new “active” folder intact.

Did you follow that!

I didn't have any problems with the first 1809 and it's updated again today with the "new" 1809.

The only issue I had was, as usual, with my 32GB drive being too small for the update however using a 16GB dongle for updates these days seems to be the resolution.

What I didn't like is that they enabled several apps by default plus the rhs notifications bar automatically showing MS News, I soon found how to switch that off, darned annoying.

Depending on your Windows version or your domain Administrator's settings you may want to delay all Microsoft updates. Not all my machines can do this, but where I can I try to wait at least a few weeks before allowing MS to update the OS. This isn't the first time they've had a major update that caused problems.
