Bugs

 * Some key functionality to enable end-to-end testing of Cluster Sets scenarios are not present in this build.
 * When the Windows Preinstallation Environment is run from a local drive, the EFI partition the contains the WinPE image has no drive letter assigned.
 * Calling into the firewall service may cause network-using apps to freeze until the system is rebooted. This happens because of an application hang end task error (0xCFFFFFFF) in the Windows firewall API library (FirewallAPI.dll). It occurs when said library is blocked on an advanced local procedure call (ALPC) while it attempts to diagnose a connection failure and retrieve information during network isolation.
 * You may get a blue screen of death during volume repair.
