"Windows cannot reboot the registry"

[TripleJ]

I have a friend who seems to be able to stuff up her computer on at least a weekly basis. But I can't figure this one out.

It says that "Windows cannot reboot the registry". She was about to do something to the registry!! :Q lol

She also says it asks her to reboot to command prompt. She hasn't the foggiest of what to do there either.

Does anyone know what the problem may be?

Thanks.
