The REG_DWORD value `AutoReboot` stored in the registry key `HKLM\SYSTEM\CurrentControlSet\Control\CrashControl` (used as a boolean value), controls whether to automatically reboot the operating system at the end of the crash dump, after a bugcheck. ReactOS doesn't currently implement crash dumps, so only the auto-reboot is done. (The reason of the apparent redundant `Reboot` variable in KeBugCheckWithTf() is because that variable would be updated on return by the not-yet-existing crash-dump helper routines called from there.)
