Windows stuck in reboot loop due to existing Scheduled Task

Is there a way to stop Task Scheduler on startup?

I ask because I have made mistake while creating task, and now my computer shuts down after 1 min. That's not enough time to open the Task Scheduler and turn it off.

• Start the computer in Safe Mode.
• Check these locations for your task:

%systemroot%\System32\Tasks
%systemroot%\Tasks

• Once you've identified it either delete it, or copy it someplace else.
• Reboot Windows into Normal Mode.

You can boot into safe Mode. Once there use regedit to delete the offending task. It should be in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\***yourtaskname***
