I have been using MikTeX for over 15 years (with LyX for over 10 years),
and have never experienced such an automatic update that some have
ascribed to it. To make sure, I have checked on the MikTeX issue
tracker, with the following outcome. A user can configure MikTeX to
install on the fly LaTeX-packages that are required by his/her document.
But MikTeX does never update automatically its executables or packages
that have previously been installed; this has to be done manually
through the MikTeX console.

In the past LyX was available in a bundle with MikTeX. During install,
the LyX-installer did update MikTeX; so it was not MikTeX, but the
LyX-installer that did the update, and caused problems.
I checked the relevant bug report that concerned LyX to refresh my
memory, and you are right indeed. MikTeX did break itself in a non easy
to fix way, but it was because the update was triggered by our installer.
