D3D resource create fail and crash

Hi,

I have the question that if I CreateDevice of D3D on the different OS, there will get different results.

In the Win 7, when I create device to 72~75, it will create fail and  crash in the Init() function.

But in the others OS(win 8/win 10), it can create more than 200.

Can I use any tool to get the resource information about this issue.

I try to find any information from DXCapsViewer.exe, but failed, can you give me some suggestion, thanks

m_pD3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING | D3DCREATE_FPU_PRESERVE, &d3dpp, &m_pDevice));
