For Windows, simply use the freely available putty application. With putty, you can ssh into your ATV2 and issue it commands like you do with the Mac Terminal app.
Because, if you manage to jailbreak the ATV2 entirely on Windows...the hard part is technically over. It's silly to have to put together a hackintosh for the sake of ssh'ing into your ATV2. There's plenty of ssh clients on the windows side. But give putty a try first. It's pretty bullet proof.

More instructions for those who needs it
----------------------------------------
1. Download putty.exe from the
official site.
2. Save it to a location that is already in your enviroment "path" variable. I like c:\windows (This allows you to execute it from anywhere since c:\windows is already in your PATH environment variable)
3. Type the following into Start/Run or command prompt to ssh into your AppleTV. Make sure to replace the IP address with your ATV2's IP address.
(Vista and Windows 7 will pop up a security dialogue and ask you if you want to allow putty to run)
If it's your first time connecting, accept the prompt about saving the ssh key.
Next, you will be prompted for a password. The default password is:
alpine
That's all there is to it. Now you can issue commands to install XBMC by following the directions on the
official wiki for XBMC on ATV2.
A reminder for the truly newb... the "$" should not be copied as it denotes the command prompt in root mode. You should be able to copy and paste everything after the "$" as instructed on the wiki.
Lastly, if you just type putty, you will get the putty GUI in case you want to save a session for yourself or feel safer seeing a graphical interface.
