I don't use Windows so forgive my ignorance but... wouldn't remotely editing the registry of another windows machine on the same network require you to authenticate to that machine?

Check that whatever you were doing didn't set the led to blink red. Some of the payloads I've seen do that in certain conditions (such as not obtaining an ip, in the nmap payload). The red flash only means recovery mode if it happens while it's booting.
