No, Netem is a Linux system. It won't work on Windows.
However, what you can do is install Netem ona linux box and use that as a router - you get better results as you're not affecting your Windows machines at all, but the netem appliance is restricting your network traffic just like you'd get in a real WAN environment.
Alternatively, use wanem which is a livecd (so self-contained and easy to set up) of a netem-style network emulator.

Here are a hand full of links for network emulators:
If by network emulator you mean a piece of software that allows you to telnet, or ssh then I recommend you look at PuTTY.
