Black Screen of Death in Vista

Windows Vista may, after a reboot, boot up to nothing but a black screen with a white mouse cursor. Safe mode does the same thing. Last Known Good Configuration and System Restore do not fix is (except in some rare cases where restoring to at least a month ago does).

This is seemingly related to the Remote Procedure Call service (RPC) being changed from running as the NetworkService account to LocalSystem account. No one has yet figured out what triggers this change.
