Symptoms

When you repeatedly create and then delete an instance of a Network Driver Interface Specification (NDIS) miniport driver in Windows Embedded Compact 7, a memory leak may occur in the NK.exe process.

Note The NK.exe process is the core process of the Windows Embedded Compact 7 system.

For example, this issue may occur when you repeatedly perform one of the following operations to dynamically create and then delete a new NDIS device instance:

  • You call the NdisRegisterAdapter and NdisDeregisterAdapter functions.

  • You send the IOCTL_NDIS_REGISTER_ADAPTER and IOCTL_NDIS_DEREGISTER_ADAPTER NDIS DeviceIoControl requests.
