Shutting down Windows PC via MetaCard

[Thomas McCarthy]

I guess the subject line pretty much says it all. I'm a teacher and run some stack for my students to use. Today as we finished up, I thought it would be nice to press a button and turn all the machines (or selected ones) off without physically moving (save those calories!)

Anyone know how to do it? I imagine it would be some "shell" command

Cheers,
Tom McCarthy
