Thanks to the answer in this thread I found out that my Intel GPU driver is causing memory leak (4.1GB of non-paged pool). I tried to install various versions of driver and this problem comes back every install of drivers. On Windows 10 default driver non-paged pool is 110MB, but when I start installing driver it comes back to 4.1GB (screen goes black for a second during install and it's 4.1GB non-paged pool again). I tried installing driver from Snappy Driver Installer and from official Intel website (Beta 15.40.26.4474, 15.40.25.4463, 15.40.22.4424 i 15.40.10.4300). The result was the exact same every single time.
I was reinstalling the driver in this way:
1. Went to Safe mode
2. Uninstalled driver using Display Driver Uninstaller (from guru3d.com)
3. Restarted to Win 10 normal mode (every time i restarted the non paged pool was about 110MB)
4. Started installation of driver
5. During installation screen went black and non-paged pool was 4.1GB again.

Any thoughts how to fix this?

PS. If this may have something in common with what happens, I reduced my system partition size to 250GB (via Partition Master, because built-in system tool didn't let me reduce this partition as much as I wanted) and soon after graphic driver crashed (screen even didn't go black IIRC, just information about crash showed up). I also updated my drivers via Snappy Driver Installer, but I don't remember if it was before or after the driver's crash.

In my case it was problem with allocating too much RAM to iGPU so driver couldn't handle it. It seems driver cannot allocate more than 512MB VRAM. I wanted more VRAM for games and i created this problem by accident.
I fixed this by going to UEFI, then to "Integrated Peripherals" and i changed RAM assigned to iGPU to 512MB and memory leak disappeared.

If you using WPF and you change a lot of graphic elements then some graphic drivers have problems (e.g. from Siemens IPCs)

You can solve it with the RegistryKey described here
