Windows eating up 21 Gb of ram

  memory-leaks, ram, resources, windows

I bought a new PC that has 40gb of ram, and just installed a clean windows on it, with only chrome and few tabs open my ram usage is 21 GB ! the numbers in task manager don’t add up to even 30% of this usage, chrome is only using 1gb of ram and the other processes are using less. I searched and followed many tutorials to track the problem that seems to be in the paged pool, I used poolmon.exe and I found the most 2 using paged pool memory are MmSt and Ntff which are related to windows file management and ntfs filesystem, most tutorials and answers suggest that high usage is because of a faulty driver or something similar and updating or removing it fixes the issue. what should I do ? remove windows ?
