Come si spegne da remoto un computer Windows senza il supporto del desktop remoto su una rete domestica?

I have an older Dell Dimension desktop that originally had Windows XP running on it but has recently been upgraded to Windows 8.1. I plan on using it as a media server running Plex so that I can easily move files onto it over my home network and update the library through the Plex web administration interface.

I also want the ability to shut the computer down when I am not using it. I do not want to plug a monitor and keyboard into it, so I am not sure how to do this since remote desktop support seems to only be available in Windows 8.1 Pro for some reason.

The only thing I can think of is to set up a web server that runs some highly-trusted code that can invoke the shutdown command on the host, but I believe there must be a simpler way to do this.

VNC (TightVNC or one of the many other flavors available) is a freeware graphical remote control solution like the remote desktop feature you wanted to use and it supports Windows 8.x. VNC via an SSH tunnel is recommended for usage across the Internet.

Alternatively, if you enjoy the command line, try running an SSH server on your media server. You can then run an SSH client (like PuTTY) which would allow the automation of file transfers and access to the command line with high security. You can use the shutdown command inside of an SSH session or even directly from another Windows machine. This allows you to shut down or restart a local or remote computer.

For a low-tech solution, try holding the power button down quickly for a second or less (not the five seconds for a hard power off). Windows should shut down gracefully or go into standby mode (depending on the configuration).
