disabling automatic restart on system failure from the registry

If for some reason you are completely unable to disable "automatic restart on system failure" on a system which will not boot, there is another way. It's possible to disable this from the registry, which can be edited offline with the appropriate tools, for example from a system recovery boot disc.

Open regedit and navigate to :

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Crashcontrol
(note this key, specifically "currentcontrolset" may not appear depending on circumstances)

and any/all of

HKEY_LOCAL_MACHINE\System\ControlSet001\Control\Crashcontrol
HKEY_LOCAL_MACHINE\System\ControlSet002\Control\Crashcontrol
HKEY_LOCAL_MACHINE\System\ControlSet003\Control\Crashcontrol
etc...

under each one, change the value for "autoreboot" to zero.

the usual registry disclaimer applies, if you mess around with stuff you don't understand you can and probably will trash your system...!
