How can I make my Mac shutdown a Windows PC when my UPS signals power loss? I have an APC UPS connected to my iMac that's set to shutdown after 1 minute of running on UPS power. I also have a Windows 10 PC plugged into the UPS that I'd like shut down as well. Is there a way to send a shutdown command from my Mac to the Windows 10 PC telling it to shut down as well when a power loss is detected?
Take a look at this SuperUser question How can I shutdown a Windows machine remotely from OS X?. It recommends installing and using the net command:

net rpc shutdown -I xxx.xxx.xxx.xxx -U username%password


You can then use a tool like Power Manager to trigger the net command when your UPS detects the power failure.



I work on Power Manager, so feel free to ask technical questions.
