Windows executable whose name suggests a utility for scheduling automatic shutdown, about 9.85 MB.

A tool like this might be used during burn-in or stability testing to power a machine off after a set time. As with any unidentified executable, scan it with antivirus software and run it first in an isolated environment or virtual machine.
