When you try to shut down a computer that is running Windows Preinstallation Environment (Windows PE) 2.0, the computer stops responding (hangs). This problem occurs if the computer is running the Microsoft Storport driver (Storport.sys).
This problem occurs because the Storport.sys driver in Windows PE 2.0 incorrectly forwards interrupts to the miniport when the PCI bus is in the D3 (device off) state.
