Not in Windows unless you have WOL installed.

I'm using Windows and git with ssh keys and haven't managed to install WOL.

What you need is to install Git for Windows. It will include ssh-keygen (if it's not already there) and you can do the usual dance.

Windows comes with ssh by default these days so you can easily ssh-keygen. Doesn't need WOL as I used that without WOL.
