I'm finding that I have to restart my computer fairly often ever since upgrading to Windows 10, due to a memory leak in the non-paged pool.  After doing research and running poolmon -b, I found that the problem tag is RtlW, but so many drivers use that tag that I can't see the full list with findstr to find and fix the cause.  I'm at a roadblock and need some assistance.  What should I do next?

When does it happen?

 

I'm asking because of things like this

and this with the Killer Network Driver

That's one problem.  I have so much RAM (32 GB) that it's hard to tell when it starts.  I do tend to notice it when I'm playing video games for extended periods of time, but closing and reopening the games does not clear up the memory.  At that point the memory leak is about 29 GB in size.

 

EDIT: I just ran poolmon again after a restart and a few hours of idling, and RtlW is leaking about 1 GB already.

We're at a 3.5 GB leak now and all I've done since the restart was web browsing and playing a video game for a couple hours.

More idle time, and we're now at 6.75 GB.  Leak definitely seems to happen on its own with time.

The memory usage somehow shrank during today's idle time to about 550 MB, so I don't know what to make of this.

I'm still having this issue, and I'm completely stumped as to what to do next.
