Whether or not this is an issue depends on what users do with their
computers. If they're playing around with beta releases, as in the
Insider Development program, it's not a good idea to use a computer
with critical files on it. As for the rest who use Win10, the
update has not been distributed, so it's a non-issue.

wrong. 1809 was released last week to the public then later pulled on
friday after people lost data. it was not an insider build.

It was not "distributed". It was available for "optional" download
only.

I got it automatically on a laptop of mine.

yep. same here (although not a laptop).
