Hello,
I have VERY odd behavior with RAMMap showing a ton of unused active memory and it grows slowly over time and I figured out that a lot of it is caused by me opening my browser (Brave) it also happens with a clean install of chrome. Every time I open Brave, I see it grow by about 6 MB. You can understand how this can grow over the course of a few weeks to make it seem like memory usage is higher then it should be.
Here is a picture of RAMMap:
The only way I can get rid of it is to restart. I have also check tools like PoolMonX to see if it is a driver but nothing there. I also reinstalled Windows only a few days ago in hopes of fixing this issue. Everything else looks good but this is just bugging me to no end. I also have a ETW Heap Trace of when I launch brave and can give that if needed.
