Default W10 / Shutdown / Hyberfil.sys

One laptop always needs minutes to shut down if the hyberfil.sys is activated.
This only happens on that laptop.
All other machines are shutting down normal.

Is there a tool out to log the activities during the shutdown?
I want to know who is writing so much data to the hyberfil.sys at shutdown.

What you would probably want, is a "memory map".

The OS only hibernates stuff it knows about.

It has to back up any memory in use, and ignore
memory not in use, during the hibernation process.
It doesn't just blindly compress the contents of
every memory stick, as that would take too long on
average.

And while the columns in Task Manager "tell a story",
remember that this is Windows and plenty of stuff
that matters, "isn't on the map". I run into this
all the time, with perfmon.msc behaviors not
counting activities on the machine. (You can have
disk I/O, and it doesn't show in a graph.)

If a driver leaked memory in kernel Ring 0, how
would we see that ? Maybe poolmon could see it.
I bet the OS does back that up during hibernation,
even if the leaked content has no value whatsoever.

Some OSes have a paged and unpaged pool indicator
in Task Manager.

I don't have a magic wand for this question. I would
be hard pressed, to figure out every little chunk
of memory that is being allocated.

If you were running a RAMDisk in regular system memory,
then hibernation would be forced to record that. The
allocation in Task Manager, would only show in terms
of the "Memory Pane" total memory used.

Are you sure the other systems are hybernating and not just sleeping? Going
to sleep takes only a couple minutes.
