CORE-17561, CORE-17932, CORE-18221 Do it at each system startup instead: Remove old DirectX initialization code. It's now outdated and not needed anymore. Previously, the corresponding hackish intEnableReactXDriver() function did two things: load dxg.sys and enable DirectDraw. Now loading DirectX graphics is done during WINSRV initialization, and enabling DirectDraw is called during each (and also first) display mode switch, as in Windows. As debug analysis proves, there are no any other calls in NtGdiDdCreateDirectDrawObject, besides the corresponding DXG function.
