It is funny with 4Gb video card in windows 7 I can mine, but when I install windows 10 on the same computer I can not mine anymore because I get error
CUDA error - cannot allocate big buffer for DAG.

anyone knows why is that happend?
Can I disable something in windows 10?

This does sound like a virtual memory problem.

It's a simple enough procedure, but if you need help configuring your VM in Windows, I recently updated my guide here: https://www.cryptoyeti.com/cannot-write-buffer-for-dag-error/

Its not a virtual memory problem. Windows 10 has some system resources or cache that it uploads to the GDDR whenever windows starts and along with the large DAG, it exceeds the physical memory requirements on the GPU, its not the virtual memory.

There are 3 solutions to this

1) Put a 8GB video card in the main PCIe slot of the motherboard, its usually the one that is PCIe 3.0 x16, usually label PCIe slot 0. You can put the 4GB in the other slot and it should work.

2) Use Windows 7, however there is a max of 4 GPUs limit and no more security updates.

3) Use Linux. There is some learning curve to this. My biggest issue was correctly installing the display drivers.
