windows - Huge paged pool probably caused by fltMgr.sys , what to do?

I found that my Windows machine was using over 95% of RAM constantly and it was often slow. And I found that "Paged Pool" always used over 10GB RAM. Here's 2 screenshots of task manager:

I followed the instructions in answer https://superuser.com/a/949246/160304 and here's what I found:



  • Use poolmon to sort paged pool usage by bytes, the thing which uses around 12GB(I believe) has tag FMfn:

  • Find out which driver is using tag FMFn, looks like it's fltMgr.sys:

  • Find out what fltMgr.sys is, it's from microsoft:

Now I don't know what to do next. I'd appreciate some ideas.
