If your recovery procedure involves restoring an earlier version of the
registry then this could cause the setting to revert. Then you wouldn't
know whether or not it had changed before the problem occurred.

Of course, it's always possible that the registry is getting corrupted, for
instance as a result of a memory error. However in this case I would expect
that the symptoms were more variable and much more widespread.

Consider what utilities you are running that might be trying to 'optimise'
your system behind your back, or utilities that need to manipulate Windows'
settings for their own purposes, such as diagnostics, and may not be
restoring things to how they were.

I still have not received a workable answer.
I want to disable drive write-behind and make the settings stick.
How do I do this? Thanks.
